Spectral and thermal studies for some transition metal complexes of bis(benzylthiocarbohydrazone) focusing on EPR study for Cu(II) and VO2+

The coordination behavior of bis (benzylthiocarbohydrazone) as a macrocyclic ligand (H2BBTC), towards Co(II), Ni(II), Cu(II) nitrates, Cd(II) and Pt(IV) chlorides as well as VO2+ sulphate has been investigated. The elemental analysis, magnetic moments, spectral (UV-vis, IR, 1H NMR and EPR) with thermal studies were used to characterize the isolated complexes. The IR spectra showed that the ligand acts as a binegative hexadentate donor through NH groups and thiol S atoms. Electronic and magnetic data proposed the octahedral structure for all complexes under investigation, except VO2+, is a square-pyramidal geometry. EPR spectra for VO2+ and Cu(II) reveal data confirmed the proposed structures. The ionization constants (pK1 = 8.3 and pK2 = 7.7) of the ligand and the stability constants of its complexes in solution were determined. The TG analysis for most complexes supports the absence of solvent molecules in or out the coordination sphere through the high thermal stability observed on the thermal curves for the investigated complexes.

Internuclear distance and effects of Born-Oppenheimer breakdown for PtS, determined from its pure rotational spectrum

The internuclear distance and effects of Born-Oppenheimer breakdown for platinum monosulfide (PtS) were investigated using a cavity pulsed jet Fourier-transform microwave spectrometer. The spectral analysis using a multi-isotopomer Dunham-type expression produced values for Y01, Y02, Y11, and Y21, along with large values for Born-Oppenheimer breakdown (BOB) parameters for both atoms of the molecule. The BOB parameters were rationalized in terms of the molecular electronic structure and nuclear field shift effects. The equilibrium bond length was also evaluated along with the vibrational frequency and dissociation energy.

Transformation of a model FCC gasoline olefin over transition monometallic sulfide catalysts

The selective HDS of FCC gasoline is a sensible option for reducing sulfur content in commercial gasoline. For such application, a minimum activity of the catalyst toward olefin hydrogenation is required to preserve the high octane number of the feedstock. The conversion of a model FCC olefin (2,3-dimethylbut-2-ene:23DMB2N) under close HDS conditions was investigated over a series of unsupported transition monometallic sulfides (FeS, Ni3S2, PdS, Co9S8, Rh2S3, RuS2, PtS, and MoS2). The results reveal for the first time that a volcano curve relationship exists between the ab initio calculated sulfur-metal bond energy, E (MS), descriptor of bulk TMS, and their activities in olefin hydrogenation under the conditions of HDS of FCC gasoline. In particular, Rh2S3, with an intermediate metal sulfide bond energy of 119 kJ/mol, was the most active catalyst in hydrogenation of the model olefin. In a similar spirit as volcano curves obtained for the HDS of dibenzothiophene and hydrogenation of toluene and recently reported in the literature, a microkinetic model furnished a rational interpretation of this trend.

Thermal decomposition of nickel(II), palladium(II), and platinum(II) complexes of N-allyl-N′-pyrimidin-2ylthiourea

Thermal decomposition of Ni(II), Pd(II), and Pt(II) complexes of N-pyrimidin-2ylthiourea (AllPmTu) have been studied by TG, DTG, and DTA and by electron impact (EI) mass spectra. The complexes have the molecular formulae as [Ni(AllPmTu)Cl2(H2O)], [Ni(AllPmTu)2Cl 2(H2O)2], and [M(AllPmTu)Cl2], where M = PdII or PtII, and [Pt(AllPmTu)2]. The TG curves show that Ni(II) complexes decompose in three stages to yield NiO as a residue, while Pd(II) and Pt(II) decompose in two stages to yield MS residues. The initial mass losses correspond to elimination of allylamine for Pd(II) and Pt(II) complexes but, allyisothiocyanate for both Ni(II) complexes revealing that sulfur atom of thiourea part is involved in coordination to Pd(II) and Pt(II) but does not to Ni(II). Kinetic parameters (E #, n, ΔH #, ΔS #, ΔG #) of the decomposition stages are determined and correlated with bonding and structural properties of the complexes. The EI mass spectra of the complexes show fragments corresponding to the evolved and intermediate species.

Synthesis and characterization of some transition metal complexes of thiosemicarbazones derived from 2-acetylpyrrole and 2-acetylfuran

Copper(II), nickel(II), palladium(II), platinum(II), and silver(I) complexes of 2-acetylpyrrole thiosemicarbazone (H2L1) and copper(II), nickel(II), platinum(II) and zinc(II) complexes of 2-acetylfuran thiosemicarbazone (HL2/su

Thermal studies of Ni(II), Pd(II), Pt(II) and Ru(III) complexes of N,N-dihexyl-N′-benzoylthiourea

Some metal complexes of N,N-dihexyl-N′-benzoylthiourea (DHBT) of the type M(DHBT)n [ M=Ni, Pd, Pt, (n=2), Ru, (n=3)] have been synthesised and studied using DTA and TG. These complexes undergo only the pyrolytic decomposition process. The orders, n, the activation energies, E, the pre-exponential factor, A, and the entropies, ΔS of the thermal decomposition reactions have been derived from thermogravimetric (TG) and differential thermogravimetric (DTG) curves. The characterisation of the end products of the decomposition was achieved by X-ray diffraction. UV-Vis and IR spectra were used for the investigation of characteristic absorption bands and the structural characterisation of ligand and the metals, respectively. Using the Coats and Redfern and Horowitz and Metzger methods performed kinetic analysis of the thermogravimetric data.

The permanent electric dipole moment of PtO, PtS, PtN, and PtC

The permanent electric dipole moments of the ground, and the low-lying excited electronic states of platinum monocarbide, PtC, platinum monoxide, PtO, and platinum monosulfide, PtS, were measured using a molecular beam optical Stark spectroscopic scheme.The determined values were (in Debye): PtO(X 3Σ-) 2.77(2); PtO(A 1Σ+) 1.15(4); PtS 1.78(2); PtS 0.54(6); PtC(X 1Σ+) 0.99(5); and PtC(A 1Π) 2.454(3).These results, along with the previous results for PtN(X 2Π1/2) 1.977(9); PtN(d 4Π1/2) 1.05(9) , are used as basis for a discussion of the nature of the electronic states.

Hexamethyleneiminecarbodithioates of Ni(II), Zn(II), Cd(II), Hg(II), Pd(II), Pt(II), Co(III), Ru(III), Rh(III) and Ir(III): Synthesis and Structure

The complexes of the type M(HMICdt)2 or 3, where M = Ni(II), Zn(II), Cd(II), Hg(II), Pd(II), Pt(II), Co(III), Ru(III), Rh(III) or Ir(III) and HMICdt(-) = hexamethyleneiminecarbodithioate, have been prepared.Their structures have been established by elemental analyses, conductance and magnetic measurements, electronic, IR, 1H and 13C NMR spectra and X-ray powder patterns.The M(HMICdt)3 type complexes have octahedral geometry.The Ni(II), Pd(II) and Pt(II) complexes have been found to be square planar whereas MS4 group seems to have a somewhat flattened tetrahedral structure in the case of Zn(II), Cd(II) and Hg(II).A secondary interaction between the S of a MS4 group and M of another complex molecule seems to exist in Zn, Cd and Hg complexes.The infrared and NMR have indicated that the CSS(-) group is symmetrically chelated with all these metal ions.
