“…These strategies undoubtedly help to shed light on the prediction, design, and synthesis of the target complexes. For example, imidazole-4,5-dicarboxylic acid (H 3 IDC), which can be partially or fully deprotonated to generate H 2 IDC 1-, HIDC 2-, and IDC 3-anions at different pH values, coordinating with metal ions to form different Metal-Organic Frameworks with interesting 0-D, 1-D, 2-D, and 3-D topologies [16,18,20]. Over the past few years, extensive investigation has focused on the construction of coordination polymers using 4,5-imidazoledicarboxylic acid as bridges of interest for the following reasons: (1) they are especially good multidentate N-or O-donors with various coordination modes to metal ions and the ability to act as H-bond acceptors and donors to assemble various supramolecular structures; (2) they can be partly or fully deprotonated dependent on the pH, providing various acid-base type coordination modes; (3) the two nitrogen's in the imidazole ring can orient the coordination, consistent with Si-O-Si bond angles in zeolites or M-IM-M bond angle in zeolitic imidazolate frameworks (ZIF) [16,[18][19][20].…”
