Diaqua[N,N'-bis(3-carboxyprop-2-enoyl)pyridine-2,6-dicarbohydrazidato(2-)]cadmium(II) N,N-dimethylformamide disolvate

Q. Cao and D. Li

Abstract: In the title complex, [Cd(C₁₅H₁₁N₅O₈)(H₂O)₂]·2C₃H₇NO, the Cd^II ion is located on a twofold rotation axis and is seven-coordinated in a distorted pentagonal-bipyramidal manner. The asymmetric unit comprises one metal ion, one doubly deprotonated N,N'-bis(3-carboxyprop-2-enoyl)pyridine-2,6-dicarbohydrazide ligand, two coordinating water molecules and two dimethylformamide solvent molecules. In the crystal, a two-dimensional network is formed through N-HO and O-HO hydrogen bonds.
