Bis(Μ-4-Methyl­Benzoato)-Κ3 O,O′:O;Κ3 O:O,O′-Bis­[Aqua­(4-Methyl­Benzoato-Κ2 O,O′)(Nicotinamide-Κn 1)Cadmium]

Abstract

In the dinuclear centrosymmetric title compound, [Cd2(C8H7O2)4(C6H6N2O)2(H2O)2], the CdII ion is chelated by two carboxyl­ate groups from 4-methyl­benzoate anions, and is further coordinated by one nicotinamide and one water mol­ecule; a carboxyl­ate O atom from an adjacent 4-methyl­benzoate anion bridges to the CdII ion, completing the irregular coordination sphere of the seven ligand atoms. In the crystal, inter­molecular O—H⋯O, N—H⋯O and weak C—H⋯O hydrogen bonds link the mol­ecules into a three-dimensional network. The methyl­benzene moiety of one bridging 4-methyl­benzoate anion is disordered over two orientations of equal occupancy.
