title: Tetra-aqua-bis(5-hydroxy-nicotinato-κN)cadmium(II).
abstract: The title compound, [Cd(C(6)H(4)NO(3))(2)(H(2)O)(4)], was obtained by the reaction of cadmium chloride with 5-hydroxy-nicotinic acid. The Cd(II) atom is located on an inversion centre and is coordinated by two N atoms from two 5-hydroxy-nicotinic acid ligands and four water mol-ecules in a distorted octa-hedral geometry. The structure is stabilized by inter-molecular O-H⋯O hydrogen bonds, forming a three-dimensional network.
