title: Diaqua-[N,N'-bis-(3-carboxy-prop-2-enoyl)pyridine-2,6-dicarbo-hydrazidato(2-)]cadmium(II) N,N-dimethyl-formamide disolvate.
abstract: In the title complex, [Cd(C(15)H(11)N(5)O(8))(H(2)O)(2)]·2C(3)H(7)NO, the Cd(II) ion is located on a twofold rotation axis and is seven-coordinated in a distorted penta-gonal-bipyramidal manner. The asymmetric unit comprises one metal ion, one doubly deprotonated N,N'-bis-(3-carboxy-prop-2-eno-yl)pyridine-2,6-dicarbohydrazide ligand, two coordinating water mol-ecules and two dimethyl-formamide solvent mol-ecules. In the crystal, a two-dimensional network is formed through N-H⋯O and O-H⋯O hydrogen bonds.
