Özet

In the centrosymmetric title structure, [Zn(C9H10NO2)(2)(C6H6N2O)(2)(H2O)(2)]-2H(2)O, the Zn II 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)degrees, while the pyridine and benzene rings are oriented at a dihedral angle of 77.10(4)degrees. The uncoordinated water molecule is linked to nicotinamide ligands by O-H center dot center dot center dot O hydrogen bonds. In the crystal, intermolecular N-H center dot center dot center dot O, O-H center dot center dot center dot O and C-H center dot center dot center dot O hydrogen bonds link the molecules into a three-dimensional network. A weak N-H center dot center dot center dot pi interaction also occurs.
