Diaquabis(5-carboxy-2-propyl-1H-imidazole-4-carboxylato-κ2N3,O4)cadmium N,N-dimethylformamide disolvate
Abstract
In the title complex, [Cd(C8H9N2O4)2(H2O)2]·2C3H7NO, the six-coordinate CdII ion is in a slightly distorted octahedral environment, defined by two O atoms from two coordinated water molecules and two carboxylate O atoms and two N atoms from two N,O-bidentate 5-carboxy-2-propyl-1H-imidazole-4-carboxylate ligands. In the crystal, complex molecules and dimethylformamide solvent molecules are linked by O—H...O and N—H...O hydrogen bonds into a two-dimensional supramolecular structure. The propyl groups of the ligands are disordered over two conformations with refined occupancies of 0.680 (7) and 0.320 (7).
