Abstract: In the title neutral mononuclear complex, [Cd(H2IDC)2(H2O)3]·H2O (H2IDC is the 4-carboxy-1H-imidazole-5-carboxylate anion, C5H3N2O4), the CdII atom is trans-coordinated by two H2IDC ligands and three aqua molecules, displaying a distorted trigonal-bipyrimidal geometry. Interestingly, H2IDC coordinates in an N-monodentate fashion to the central CdII atom, which is unprecedented. A three-dimensional supramolecular network is generated through N-HO and O-HO hydrogen bonds.
