Aqua-bis(4-formyl-benzoato-κO,O)bis-(isonicotinamide-κN)cadmium(II) monohydrate.

ABSTRACT: The asymmetric unit of the title Cd(II) complex, [Cd(C(8)H(5)O(3))(2)(C(6)H(6)N(2)O)(2)(H(2)O)]·H(2)O, contains two 4-formyl-benzoate (FB), two isonicotinamide (INA) ligands, one coordinated and one uncoordinated water mol-ecule; the FB ions act as bidentate ligands. The coordination number of the Cd(II) atom is seven within a CdO(5)N(2) donor set. Intra-molecular O-H⋯O hydrogen bonds link the uncoordinated water mol-ecules to the carboxyl groups. The dihedral angle between the carboxyl-ate groups and the adjacent benzene rings are 17.53 (13) and 16.55 (14)°. In the crystal structure, inter-molecular O-H⋯O, N-H⋯O, N-H⋯N and C-H⋯O hydrogen bonds link the mol-ecules into a supra-molecular structure. The amide group of one of the INA ligands is disordered over two orientations, with an occupa
