“…In the same way, ligands with mixed-functionalities such as pyridinecarboxylate, pyrazinecarboxylate, imidazolecarboxylate have been reported to favours the design of diverse structure of coordination compounds with fascinating potential application [9][10][11]. Furthermore, these ligands are known to possess strong and weak hydrogen bonding (such as O-H•••O and C-H••••O) and π-π stacking interactions, which in uences their biological properties [12][13][14][15].…”

In the past two decades various N-heterocyclic carboxylate coordination compounds have been synthesized with intriguing architectures and potential applications as functional materials. In this regard, two novel calcium coordination compounds [Ca(2,6-Hpdc)2(H2O)2] 1 and [Ca2(2,3-pdc)2(H2O)6]n 2 (where 2,6-H2pdc = 2,6-pyridinedicarboxylic acid and 2,3-H2pdc = 2,3-pyridinedicarboxylic acid) were grown at room temperature. The compounds were characterized using elemental analysis, Fourier Transform infrared (FT-IR) spectroscopy, thermogravimetric analysis, powder X-ray diffraction and single crystal X-ray crystallographic analysis. Compounds 1 and 2 crystallize in orthorhombic space group Pccn and monoclinic space group Pc, respectively. The structures of both compounds are stabilized by a network of hydrogen bonds arising from coordinated water molecules and carboxylate groups. Computational analysis revealed that compound 1 has a large energy gap (9.221 eV) suggesting high excitation energies and chemical hardness making it a better electron acceptor while compound 2 displayed a smaller energy gap (5.156 eV) which is indicative of a softer molecule with better polarizability and reactivity.

“…Up to date, a large number of metal-organic frameworks derived from 1H-imidazole-4,5-dicarboxylic acid (H 3 idc) have been synthesized since it is a good linker and can be successively deprotonated to generate H 2 idc -, Hidc 2-and idc 3-anions (Ghosh et al, 2009;Liu et al, 2008;Sun & Yang, 2007). Compared with H 3 idc, 2,2'-(1,3-propanediyl)bis-1H-imidazole-4,5-dicarboxylic acid (H 6 pbidc) can provide a greater tunability of structural frameworks because of the presence of the propanediyl spacer.…”

The complex molecule of the title compound, [Mn(C13H10N4O8)(H2O)2] or [Mn(H4pbidc)(H2O)2] (H6pbidc = 2,2′-(propane-1,3-diyl)bis(1H-imidazole-4,5-dicarboxylic acid), has 2 symmetry with the twofold rotation axis running through the Mn2+ cation and the central C atom of the propanediyl unit. The cation is six-coordinated by two N atoms and two O atoms from one H4pbidc2− anion and two water O atoms in a considerably distorted octahedral coordination. In the crystal, adjacent molecules are linked through O—H⋯O and N—H⋯O hydrogen bonds into a three-dimensional network.

Most of the reported imidazole dicarboxylatebased MOFs are of transition metal ions and MOFS of lanthanides are limited [4,6,23].…”

Five lanthanide(III) coordination polymers with 2-methyl-1H-imidazole-4,5-dicarboxylic acid (H 3 MIDC) and ammonium oxalate,have been prepared and structurally characterized. Single-crystal X-ray diffraction analyses reveal that 1 and 2 are isostructural, as are 3, 4, and 5. Each exhibits a 3-D open framework, which is built by a regular 2-D grid connected by HMIDC 2À and Ln(III). The luminescence and thermal properties of these complexes have been investigated as well.
