Aqua(5-nitro-1H-benzimidazole)(oxydiacetato)copper(II)

W.-J. Zhang, Y.-T. Li and Z.-Y. Wu

Abstract: In the molecule of the title compound, [Cu(C₄H₄O₅)(C₇H₅N₃O₂)(H₂O)], the Cu^II atom is coordinated by one tridentate oxydiacetate (ODA) dianion, one monodentate nitrobenzimidazole (NBZIM) molecule and one H₂O molecule, in a distorted square-based pyramidal geometry. In the crystal structure, O-HO, N-HO and C-HO hydrogen bonds link the molecules, forming a three-dimensional network. - Stacking interactions between parallel NBZIM rings consolidate the supramolecular structure [the shortest interplanar distances are 3.360 (3) and 3.269 (3) Å].
