Diaquabis(4-nitrobenzoato)zinc(II): a redetermination

H. Necefoglu, W. Clegg and A. J. Scott

Abstract: The title compound, [Zn(O₂CC₆H₄NO₂)₂(H₂O)₂], has zinc in a coordination geometry intermediate between tetrahedral and octahedral, with each carboxylate ligand forming a primary and a secondary Zn-O bond; the lengths of these differ by more than 0.5  Å. The molecule has crystallographic twofold rotation symmetry. Intermolecular hydrogen bonds are formed between the aqua ligands as donors and carboxylate O atoms as acceptors, linking the molecules together into sheets, the closest contacts between which involve the nitro groups.
