Bis[μ-4-(methyl-amino)-benzoato]-κO,O':O;κO:O,O'-bis-{aqua-[4-(methyl-amino)-benzoato-κO,O'](nicotinamide-κN)cadmium(II)}.

In the dinuclear centrosymmetric Cd(II) compound, [Cd(2)(C(8)H(8)NO(2))(4)(C(6)H(6)N(2)O)(2)(H(2)O)(2)], the metal atom is chelated by two carboxyl-ate groups from 4-(methyl-amino)-benzoate (PMAB) anions, and coordinated by one nicotinamide and one water mol-ecule; a carboxyl-ate O atom from the adjacent PMAB anion bridges to the Cd atom, completing the irregular seven-coordination geometry. In the crystal, inter-molecular O-H⋯O, N-H⋯O and C-H⋯O hydrogen bonds link the mol-ecules into a three-dimensional network. π-π contacts between the pyridine rings [centroid-centroid distance = 3.965 (1) Å] may further stabilize the structure. A weak C-H⋯π inter-action also occurs.
