Dimer Crystallization Induced by Elemental Substitution in the Honeycomb Lattice of Ru1-xOsxCl3

Substitution effects of Os for Ru in α-RuCl3 are investigated in a wide composition range of 0 ≤ x ≤ 0.67 in Ru1-x-OsxCl3by X-ray and electron diffraction, magnetic susceptibility, heat capacity, and Raman spectroscopy measurements. Apart from the Kitaev physics with antiferromagnetic interactions increasing with x, a rich phase diagram is obtained, which includes an antiferromagnetic long-range order below 12K for x ≤ 0.15, a dome-shaped spin-singlet dimer phase below 130K for 0.15 ≤ x ≤ 0.40, and a magnetic short-range order for x > 0.40. A dimerization as similarly observed in α-RuCl3under high pressure occurs in the spin-singlet phase. It is suggested that Ru-Os pairs in the solid solutions tend to form dimers with short bonds and trigger the first-order transition in the presence of pseudo-threefold rotational symmetry for dimerization around a substituted Os atom only at low substitutions. This is a rare example of molecular orbital crystallization induced by elemental substitution in a highly disordered system. The short-range order at high substitutions may be related to a random-singlet state stabilized by bond disorder in the honeycomb net.

Detuning the Honeycomb of the α-RuCl3 Kitaev Lattice: A Case of Cr3+ Dopant

Fine-tuning chemistry by doping with transition metals enables new perspectives for exploring Kitaev physics on a two-dimensional (2D) honeycomb lattice of α-RuCl3, which is promising in the field of quantum information protection and quantum computation. The key parameters to vary by doping are both Heisenberg and Kitaev components of the nearest-neighbor exchange interaction between the Jeff = 1/2 Ru3+ spins, depending strongly on the peculiarities of the crystal structure. Here, we present crystal growth by chemical vapor transport and structure elucidation of a solid solution series Ru1-xCrxCl3 (0 ≤ x ≤ 1), with Cr3+ ions coupled to the Ru3+ Kitaev host. The Cr3+ substitution preserves the honeycomb type lattice of α-RuCl3 and creates mixed occupancy of Ru/Cr sites without cationic order within the layers as confirmed by single-crystal X-ray diffraction and transmission electron microscopy investigations. In contrast to high-quality single crystals of α-RuCl3 with ABAB-stacked layers, the ternary compounds demonstrate a significant stacking disorder along the c-axis direction as evidenced by X-ray diffraction and high resolution scanning transmission electron microscopy (HR-STEM). Raman spectra of substituted samples are in line with the symmetry conservation of the parent lattice upon chromium doping. At the same time, our magnetic susceptibility data indicate that the Kitaev physics of α-RuCl3 is increasingly suppressed by the dominant spin-only driven magnetism of Cr3+ (S = 3/2) in Ru1-xCrxCl3.

Synthesis, crystal structure, spectroscopic, and photoreactive properties of a ruthenium(II)-mononitrosyl complex

A compound of formula [RuIICl(NO)(Cl-py)4](PF6)2, in which Cl-py is the 4-chloropyridine, has been synthesized in four steps and fully characterized. It crystallizes in the P1ˉ triclinic space group as [RuIICl(NO)(Cl-py)4](PF6)2·1.25H2O. Upon irradiation at λ?=?473?nm in the solid state, the N-bounded nitrosyl ligand (ground state GS: [RuII(NO)]) turns into O-bounded nitrosyl metastable state 1 (MS1: [RuII(ON)]). The population of the long-lived metastable RuII(ON) isomer is equal to 27% on powder samples, therefore 3 times less than that of the parent [RuIICl(NO)(py)4](PF6)2derivative. Spectroscopy and TD-DFT studies are proposed to find a rational for this difference at the molecular level, which is tentatively related to different UV–visible spectra in the metastable RuII(ON) isomer. Surprisingly, and while the switching efficiency of [RuIICl(NO)(Cl-py)4](PF6)2appears relatively modest, its capability for releasing the biologically active nitric oxide (NO[rad]) radical under irradiation in solution is find to be about 100 times that of the [RuIICl(NO)(py)4](PF6)2derivative.

Synthesis and characterization of rigid +2 and +3 heteroleptic dinuclear ruthenium(II) complexes

Synthesis and characterization of the dinuclear ruthenium coordination complexes with heteroleptic ligand sets, [Cl(terpy)Ru(tpphz)Ru(terpy)Cl](PF 6)2 (7) and [(phen)2Ru(tpphz)Ru(terpy)Cl] (PF6)3 (8), are reported. Both structures contain a tetrapyrido[3,2-α:2′,3′-c:3″,2″-h:2″, 3″-j]phenazine (tpphz) (6) ligand bridging the two metal centers. Complex 7 was obtained via ligand exchange between, RuCl2(terpy)DMSO (5) and a tpphz bridge. Complex 8 was obtained via ligand exchange between, [Ru(phen)2tpphz](PF6)2 (4) and RuCl 2(terpy)DMSO (5). Metal-to-ligand-charge-transfer (MLCT) absorptions are sensitive to ligand set composition and are significantly red-shifted due to more electron donating ligands. Complexes 7-9 have been characterized by analytical, spectroscopic (IR, NMR, and UV-Vis), and mass spectrometric techniques. The electronic spectral properties of 7, 8, and [(phen) 2Ru(tpphz)Ru(phen)2](PF6)4 (9), a previously reported +4 analog, are presented together. The different terminal ligands of 7, 8, and 9 shift the energy of the MLCT and the π-π* transition of the bridging ligand. These shifts in the spectra are discussed in the context of density functional theory (DFT). A model is proposed suggesting that low-lying orbitals of the bridging ligand accept electron density from the metal center which can facilitate electron transfer to nanoparticles like single walled carbon nanotubes and colloidal gold.

About trihalides with TiI3 chain structure: Proof of pair forming of cations in β-RuCl3 and RuBr3 by temperature dependent single crystal X-ray analyses

Single-crystal X-ray studies on β-RuCl3 and RuBr 3 at different temperatures verified, that both compounds are dimorphic and show reversible phase transitions at 206 K resp. 384 K. In the HT-forms the Aristo-type of the hexagonal TiI3-structure with space group P63/m c m (Z = 2, β-RuCl3 at 293(2) K: a = 6.121(2) A, c =5.655(2) A, RuBr3 at 423(3) K: 6.5215(12) A, c = 5.8851(13) A) has been found, in the LT-forms the RuBr 3-type structure, an orthorhombic distorted variant with space group Pmmn (Z = 4, β-RuCl3 at 170(3) K: a = 10.576(2) A, b = 5.634(1) A, c = 6.106(1) A, RuBr3 at 293(2) K: a =11.2561(16) A, b = 5.8725(12) A, c = 6.4987(9) A). A hexagonal closest packing of X- anions forms the basis of an arrangement of infinite chains with face-connected [RuX6/2] octahedra. While in the chains of the hexagonal HT-forms the Ru-Ru-distances are identical (d(Ru-Ru) = 2.8275(10) A for β-RuCl3, d(Ru-Ru) = 2.9425(6) A for RuBr 3), in the orthorhombic structures the chains are distorted through pairing of the ruthenium(III) atoms (d(Ru-Ru) = 2.6328(14) A / 3.0010(15) A for β-RuCl3 at 170(3) K, d(Ru-Ru) = 2.765(1) A / 3.108(1) A for RuBr3 at 293(2) K). The hexagonal metric with a/c= √3 holds also for the orthorhombic LT-forms. Large crystals and the final products of the phase transition from HT- to LT-forms are pseudomerohedral twins of three twin domains with nearly equal amounts complicating proof and analysis of the LT-forms.

α-RuCl3/polymer nanocomposites: The first group of intercalative nanocomposites with transition metal halides

Different types of polymers can be intercalated into α-RuCl3 with different synthetic methodologies. Polyaniline/α-RuCl3 nanocomposite was prepared by the in situ redox intercalative polymerization method, in which α-RuCl3 was exposed to an aniline/acetonitrile solution in open air. Water-soluble polymers such as poly(ethylene oxide), poly(vinyl pyrrolidone), and polyethylenimine were intercalated by an encapsulative precipitation method using monolayer suspensions of α-RuCl3. A modification of this method led to insertion of polypyrrole. Monolayer suspensions of α-RuCl3 can be prepared from LixRuCl3 (x ～ 0.2). The latter is produced by the reaction of α-RuCl3 with 0.2 equiv of LiBH4. The polymer insertion is topotactic and does not cause structural changes to the host. The metal chloride layers in these materials possess mixed valency. The reduction and polymer intercalation of α-RuCl3 alters the intralayer and interlayer Ru3+ (low spin d5) magnetic coupling, so that interesting magnetic properties appear in the nanocomposites. In addition, the reduction brings in free hopping electrons to the RuCl3 layers and the polymer intercalation builds up new electronic or ionic conducting channels in the galleries, so that the charge transport properties are changed dramatically. For example, LixRuCl3 shows an electrical conductivity 3 orders of magnitude higher than pristine α-RuCl3 at room temperature and Lix(PEO)yRuCl3 has an ion conductivity comparable with the best (lithium salt)-polymer electrolytes. For a comprehensive understanding of the structure of the representative nanocomposite Lix(PEO)yRuCl3, the arrangement of polymer chains inside the galleries was explored with analysis of its one-dimensional (00l) X-ray diffraction pattern. Calculated electron density maps along the stacking c-axis lead to a structural model that fills each gallery with two layers of polymer chains exhibiting a conformation found in type-II PEO-HgCl2. The most consistent PEO arrangement in the gallery generates oxygen-rich channels in the middle of the gallery in which the Li ions can reside. The new nanocomposites were characterized with thermogravimetric analysis, infrared spectroscopy, powder X-ray diffraction, magnetic measurements, as well as electrical and ionic conductivity and thermopower measurements.
