“…Taking into consideration that coordination way of lanthanide ion to carboxylate groups are chelating and bridging, the central ion may coordinate five oxygen atoms from carboxylate groups and probably four of water molecules. So the formula of complex should be [Ln 2 (PDC) 3 The compounds, after removing water molecules are stable at a higher temperature up to 573−673 K. The thermal stability in connection with crystallinity after water molecules removing, is the most important factor which conditions application of pyridinedicarboxylates as compounds for the MOF-like structure synthesis.…”

“…There is a considerable number of publications on the coordination metal-organic complexes with the ligands originating from the isomers of pyridinedicarboxylic acid [1][2][3][4][5][6]. These ligands are interesting because they contain different coordinating groups two carboxylate groups with their oxygen donor atoms and a nitrogen atom of pyridine ring.…”

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.

“…It is well known that organic polycarboxylate ligands are good building blocks for the construction of coordination polymers and multidimensional supramolecular networks [22][23][24][25][26][27][28][29]. However the coordination polymers assembled from asymmetric carboxylate ligands have been less exploited [30].…”

A new silver(I) coordination polymer, [Ag(Hcpa)] n (1), was synthesized using a flexible asymmetric biscarboxylate ligand, (4-carboxymethoxy-phenyl)-acetic acid (H 2 cpa), and Ag(NO 3 ). The acetate group is monodentate and links a Ag(I)-atom. The oxyacatate group is tetradentate and connects three Ag(I)-atoms. Each Hcpa ligand exhibits a novel pentadentate coordination mode bridging four Ag(I) ions and is 4-connected. Each Ag(I) is coordinated by four Hcpa and extend to a novel (4,4)-connected two-dimensional network that contains one-dimensional channels. 1 reveals the blue emission maximum at 446 nm in the solid state at room temperature. The X-ray power diffractions and TGA of 1 are presented.

Two compounds, Na3[Eu(DPA)3] ⋅ 14H2O and [Eu(DPA)(HDPA)(H2O)2] ⋅ 4H2O, were created and the structure determined using single crystal X‐ray diffraction. The single crystal luminescence properties were compared and related to the Eu3+ coordination geometry. The formation of single crystals from solutions of Eu(CF3SO3)3 and H2DPA was found change with the pH value of the H2DPA solution. Mixtures of Na3[Eu(DPA)3] ⋅ 14H2O and [Eu(DPA)(HDPA)(H2O)2] ⋅ 4H2O were observed with a pH ratio between the two structures. While visual inspection showed that all samples contained both Na3[Eu(DPA)3] ⋅ 14H2O and [Eu(DPA)(HDPA)(H2O)2] ⋅ 4H2O, the PXRD and luminescence data did not immediately reveal that the samples were pure. Having discovered that the samples were indeed mixtures, quantification was attempted by Rietveld refinement of the PXRD data, and the luminescence spectra were compared to those from single crystals. As the data was not found to reveal that the samples were mixtures, even though we knew that this was the case, we must urge caution when inferring structure‐property relationships from powder samples. In this case we were able to isolate monophasic systems and do a comparative study, but this requires that the samples are identified as mixtures.
