Bis[Μ-4-(Methyl­Amino)­Benzoato]-Κ3O,O′:O;Κ3 O:O,O′-Bis­{Aqua­[4-(Methyl­Amino)­Benzoato-Κ2 O,O′](Nicotinamide-Κn)Cadmium(II)}

In the dinuclear centrosymmetric CdII compound, [Cd2(C8H8NO2)4(C6H6N2O)2(H2O)2], the metal atom is chelated by two carboxyl­ate groups from 4-(methyl­amino)­benzoate (PMAB) anions, and coordinated by one nicotinamide and one water mol­ecule; a carboxyl­ate O atom from the adjacent PMAB anion bridges to the Cd atom, completing the irregular seven-coordination geometry. In the crystal, 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 = 3.965 (1) Å] may further stabilize the structure. A weak C—H⋯π inter­action also occurs.PubMedWoSScopu
