Diaqua­Bis­[4-(Dimethyl­Amino)­Benzoato-Κo]Bis­(Nicotinamide-Κn1)Zinc(Ii) Dihydrate

Abstract

In the centrosymmetric title structure, [Zn(C9H10NO2)2(C6H6N2O)2(H2O)2]·2H2O, the ZnII cation, located on an inversion center, is coordinated by two 4-(methyl­amino)­benzoate anions, two nicotinamide ligands and two water mol­ecules in a slightly distorted octa­hedral geometry. The dihedral angle between the carboxyl­ate group and the attached benzene ring is 3.09 (9)°, while the pyridine and benzene rings are oriented at a dihedral angle of 77.10 (4)°. The uncoordinated water mol­ecule is linked to nicotinamide ligands by O—H⋯O hydrogen bonds. In the crystal, inter­molecular N—H⋯O, O—H⋯O and C—H⋯O hydrogen bonds link the mol­ecules into a three-dimensional network. A weak N—H⋯π inter­action also occurs.
