Bis[μ-4-(dimethylamino)benzoato]-κ3O,O′:O;κ3O:O,O′-bis{aqua[4-(dimethylamino)benzoato-κ2O,O′](nicotinamide-κN1)cadmium(II)}

Abstract

In the centrosymmetric dimeric CdII title compound, [Cd2(C9H10NO2)4(C6H6N2O)2(H2O)2], each seven-coordinated CdII atom is chelated by the carboxylate groups of the two 4-(dimethylamino)benzoate (DMAB) anions; the two monomeric units are bridged through the two O atoms of the two carboxyl groups. In the crystal structure, intermolecular O—H...O, N—H...O and C—H...O hydrogen bonds link the molecules into a three-dimensional network. π–π contacts between the pyridine rings [centroid–centroid distance = 3.974 (1) Å] may further stabilize the structure. Weak C—H...π interactions are also observed.
