“…Coordination polymer design depends not only on the chosen metals and organic linkers but also on the reaction conditions like temperature, solvents, and counter ions. Polycarboxylate ligands have been often used as good building blocks to construct transition metal or lanthanide coordination polymers [6][7][8][9][10][11][12][13][14][15][16]. In this ligand class, positional isomers of pyridinedicarboxylate anions, such as 2,3-, 2,4-, 2,5-, 2,6-, 3,4-, and 3,5-pdc 2− (chart 1), are representative of hybrid spacers (N,O-donors), frequently applied to achieve varied coordination polymers or metal-organic frameworks within supramolecular arrangements [17].…”

Two new complexes involving 3,4-pyridinedicarboxylic acid (3,4-H 2 pdc), copper(II) and cobalt(II) complexes, {[Cu(3,4-Hpdc) 2 (H 2 O) 2 ]·2dmso} n (1) and {[Co(3,4-Hpdc) 2 (H 2 O) 2 ]·2H 2 O·2dmso} n (2) (dmso = dimethylsulfoxide), have been synthesized by the diffusion method and characterized by elemental analysis, IR spectroscopy, thermal analysis, powder and single-crystal X-ray diffraction analysis, and electron paramagnetic resonance (EPR). In both compounds, the metal coordination sphere is composed of a trans-MO 4 N 2 core and adopts a distorted octahedral geometry in accordance with X-ray diffraction and EPR results. 3,4-Hpdc − ligands bridge the metal centers giving two-dimensional (2-D) coordination polymers with four-connected uninodal nets of (4,4) topology.

“…In the structure of d-metal quinolinate complexes the metal ions, as the coordination centre, have the coordination number 6 for example Cd(II) [19,20], Zn(II) [20][21][22][23], Mn(II) [21,24,25], Co(II) [21,26]; Ni(II) [21,23], Ag(I) [27] and in some cases coordination number (CN) is 4 for example in the copper(II) [28] or Ag(I) [29] complexes. Nitrogen donor atom of pyridine ring always takes part in coordination of transition metal ions, but behaviour of each of two carboxylic groups of ligands is different in the structures of complexes.…”

“…In the coordination metal ions there can sometimes take part only one carboxylate group of ligand. It might be monodentate [19,21,25,27,28] or bidentate by two oxygens atoms [29] or by only one oxygen atom [20]. When two carboxylate groups take part in metal coordination, they can be either monodentate [19,25,28] or bidentate [20,24,28].…”

The lanthanide(III) complexes with 2,3-pyridinedicarboxylate ligand (PDC) were obtained as crystalline compounds from the water solutions. These compounds form the series of Ln 2 (PDC) 3 · nH 2 O. All compounds are stable in air and insoluble in both water and common organic solvents. The hydrated complexes have been characterized by elemental analysis, thermal analysis (TG/DSC/DTA, and TG−FT-IR), FT-IR spectroscopy and X-ray analysis. 2,3-pyridinedicarboxylates of lanthanides(III) are stable in air below 313−323 K. Upon heating, hydrated complexes lose crystallization and lattice water in two steps. The values of dehydration enthalpy complexes are calculated from the DSC curves. The anhydrous compounds are stable at the temperature from 473 K to about 623 K and when heated they decompose to lanthanide oxides. Thermal and spectroscopic studies are essential for further studies and classification of compounds as MOF-like structures.

“…Recently, our research group has embarked on a comparative study of coordination chemistry of calcium and cadmium model complexes with N,O-biologically important ligands to find differences and similarities related to their thermal stability and molecular structures [1,2]. The similarities presented by Ca(II) and Cd(II) ions (they show similarity in their radius 0,95 and 1,00 Å ) favor the exchange of the metals in the biological system.…”

“…In this article, we report an alternative, non-hydrothermal preparation which has afforded 2 and 3 in high yield. Bearing in mind that the coordination ability of the carboxylate ligands toward metal ions frequently depends on hydrothermal or non-hydrothermal methods used to prepare the complexes [1,[5][6][7][8], we investigated the crystal structure of obtained compounds with X-ray crystallography. By comparing the crystallographic data, it can be seen that the crystal structure of the obtained complexes look similar to those reported in the literature [3,4].…”

The synthesis and characterization of cadmium(II) and calcium(II) complexes with N,O-bidentate ligands derived from pyrazinecarboxylic acid (3-hydroxy-2-quinoxalinecarboxylic acid HL 1 , pyrazine-2-carboxylic acidwere studied by elemental analyses, IR, Raman spectroscopy and thermogravimetric methods (TG, DTG, DSC). In addition, the molecular structure of complex 1 has been determined by X-ray single crystal diffraction. Thermal analysis reveals a decomposition process of 1, 3 complexes in multiple stages. The data obtained from TG and DSC curves for 1, 3 confirm not only the presence but also the nature of water (crystallization and coordination) and the stoichiometry of the studied metal complexes. The results of thermal studies are in good agreement with their crystal structures. Thermal behavior of complex 2 indicates a single complete decomposition process of the sample. In addition, complex 2 as a coordination polymer is the most stable all of them and the thermal stability of the obtained complexes can be ordered in the following sequence: 1 \ 3 ( 2.
