Abstract

In the title centrosymmetric binuclear Cd-II compound, [Cd-2(C7H5O3)(4)(C6H6N2O)(2)]center dot 4H(2)O, the six-coordinated Cd-II atom is chelated by the carboxylate groups of the two 3-hydroxybenzoate (HB) anions; the two monomeric units are bridged through the two O atoms of the two carboxylate groups. In the crystal, O-H center dot center dot center dot O, N-H center dot center dot center dot O and C-H center dot center dot center dot O hydrogen bonds link the molecules into a three-dimensional network. pi-pi Contacts between the pyridine rings and between the benzene rings [centroid-centroid distances = 3.770 (1), 3.769 (1) and 3.632 (1) angstrom] may further stabilize the structure.
