Synthesis, crystal structures and properties of a series of three-dimensional lanthanide coordination polymers with the rigid and flexible mixed dicarboxylate ligands of 1,4-benzene dicarboxylic acid and succinic acid

A series of new lanthanide coordination polymers, with the formula [Ln(Suc)0.5(p-BDC)] (Ln = Eu (1), Sm (2), Tb (3), Pr (4), Ho (5); H2Suc = succinic acid; p-H2BDC = 1,4-benzene dicarboxylic acid), have been synthesized un

Two novel R- and S-malato-bridged coordination polymers by reacting lanthanide chloride and maleic anhydride, 1,10-phenanthroline at hydrothermal condition

Two less common lanthanide coordination polymers, [Ln2(fum)(malate)2(phen)2]n ·n1.25H2O (Ln=Eu, 1; Pr, 2. fum=fumarate, phen=1,10-phenanthroline) were synthesized and characterized by IR spectra and X-ray crystallography. Single crystal X-ray diffraction analysis shows that complex 1 is isostructural with complex 2. In the two complexes, we found a pair of enantiomers (R-malate and S-malate) which are obtained by addition reaction between maleate and water and fumarate which result from configurational tranformation of maleate. The two structures consist of coordination polymer chains along the c-axis which are held together solely through hydrogen bonding and π-π stacking. Three-dimension supramolecular structures are formed through the two types of weak interaction. The IR data are also described and compared with those of other similar complexes.

Preparation, crystal structure, and magnetism of [(CH3)2NH2][PrCl4(H 2O)2]

The complex water containing chloride [(CH3)2NH2][PrCl4(H 2O)2] has been prepared for the first time and the crystal structure has been determined from single crystal X-ray diffraction data. The compound crystallizes orthorhombically in the space group Cmca (Z = 8) with a = 1796.6(2) pm, b = 940.7(1) pm, and c = 1238.4(2) pm. The anionic part of the structure is built up by chains of edge-connected trigondodecahedra [PrCl6(H2O)2]3- according to [PrCl4/2Cl2(H2O)2]-, which are held together by dimethylammonium cations ([(CH3)2NH2]+). In order to study the interactions between the praseodymium cation (Pr3+) and the ligands magnetic measurements were carried out. The magnetic data were interpreted by ligand field calculations applying the angular overlap model.

Coordination polymers based on inorganic lanthanide(III) sulfate skeletons and an organic isonicotinate N-oxide connector: Segregation into three structural types by the lanthanide contraction effect

Fourteen three-dimensional coordination polymers of general formula [Ln(INO)(H2O)(SO4)]n, where Ln = La, 1·La; Ce, 2·Ce; Pr, 3·Pr; Nd, 4·Nd; Sm, 5·Sm; Eu, 6·Eu; Gd, 7·Gd; Tb, 8·Tb; Dy, 9·Dy; Ho, 10·Ho; Er, 11·Er; Tm, 12·Tm; Yb, 13·Yb; and Lu, 14·Lu; INO = isonicotinate-N-oxide, have been synthesized by hydrothermal reactions of Ln3+, MnCO3, MnSO4·H 2O, and isonicotinic acid N-oxide (HINO) at 155 °C and characterized by single-crystal X-ray diffraction, IR, thermal analysis, luminescence spectroscopy, and the magnetic measurement. The structures are formed by connection of layer, chain, or dimer of Ln-SO4 by the organic connector, INO. They belong to three structural types that are governed exclusively by the size of the ions: type I for the large ions, La, Ce, and Pr; type II for the medium ions, Nd, Sm, Eu, Gd, and Tb; and type III for the small ions, Dy, Ho, Er, Tm, Yb, and Lu. Type I consists of two-dimensional undulate Ln-sulfate layers pillared by INO to form a three-dimensional network. Type II has a 2-fold interpenetration of 3D herringbone networks, in which the catenation is sustained by extensive π-π interactions and O-H...O and C-H...O hydrogen bonds. Type III comprises one-dimensional chains that are connected by INO bridges, resulting in an α-Po network. The progressive structural change is due to the metal coordination number decreasing from nine for the large ions via eight to seven for the small ions, demonstrating clearly the effect of lanthanide contraction. The sulfate ion acts as a μ4- or μ3-bridge, connecting two, three, or four metals, and is both mono- and bidentate. The INO ligand acts as a μ3- or μ2-bridge with carboxylate group in syn-syn bridging or bidentate chelating mode. The materials show considerably high thermal stability. The magnetic properties of 4·Nd, 6·Eu, 7·Gd, and 13·Yb and the luminescence properties of 6·Eu and 8·Tb are also investigated.

Hydrothermal synthesis and structural characterization of new lanthanide coordination polymers with pimelic acid and 1,10-phenanthroline

This paper presents three new lanthanide coordination polymers [Pr 2(pim)3(phen)2(H2O)] n·3nH2O (1) (H2pim=pimelic acid; phen=1,10-phenanthroline) and [Ln(Hpim)(pim)(phen)]n·1. 5nH2O (Ln=Nd, 2; Er, 3) prepared by the hydrothermal reaction. The structural details of complexes 1, 2 and 3 are reported. In complex 1, the Pr(III) ions are bridged by pim in three modes to form 2D layers. Adjacent layers are assembled by hydrogen bonds and π-π stacking between phen ligands into a 3D network. In complex 2, the Nd(III) ions are connected by pim and Hpim in two modes into 1D chains. Hydrogen bonding and π-π stacking between chains result in a 3D supramolecular structure. Single crystal X-ray diffraction analysis shows that complex 3 is isostructural with complex 2.

Three new lanthanide coordination polymers containing isophthalate and 1,10-phenanthroline

Three lanthanide coordination polymers were prepared by hydrothermal synthesis and characterized by single-crystal X-ray diffraction. [Pr 2(mBDC)3(phen)(H2O)]n·0.5n H2O (1) (mBDC = isophthalate, phen = 1,10-phenanthroline) exhibits two kinds of metal environments (coordination numbers 7 and 8). In complex 1, mBDC ligands adopt the tetradentate (bridging and bridging) coordination mode and connect Pr ions into an undulating layer, and a 3D supramolecular structure is formed via hydrogen bonds between adjacent layers. [Tb4(mBDC) 6(phen)]n (2) has three types of metal environments (coordination numbers 6, 7 and 8) and is composed of a 3D network formed by mBDC linking Tb ions via tetradentate (bridging and bridging) and pentadentate (bridging/chelating and bridging) coordination modes. There are two kinds of small quadrilateral channels along the a-axis. [Er4(mBDC) 6(phen)]n (3) is isostructural to complex 2.
