Abstract

The title compound, [CdCl2(C6H7N3O)(2)], was obtained unintentionally as a product of an attempted reaction of CdCl2 center dot 2.5H(2)O and picolinic acid hydrazide, in order to obtain a cadmium(II) complex analogous to a 15-metallacrown-5 complex of the formula [MCu5L5]X-n, with M = a central metal ion, L = picolinic acid hydrazide and X = Cl- , but with cadmium the only metal present. The coordination geometry around the Cd-II atom can be considered as distorted octahedral, with two bidentate picolinic acid hydrazide ligands, each coordinating through their carbonyl O atom and amino N atom, and two chloride anions. In the crystal structure, intermolecular N-H center dot center dot center dot Cl and N-H center dot center dot center dot N hydrogen bonds link the molecules into a two-dimensional network parallel to the ( 100) plane. The pyridine rings of adjacent networks are involved in pi-pi stacking interactions, the minimum distance between the ring centroids being 3.693 (2) angstrom.
