Diaquabis(4-methylbenzoato-κO)bis(nicotinamide-κN1)manganese(II)

Abstract

In the mononuclear title complex, [Mn(C8H7O2)2(C6H6N2O)2(H2O)2], the MnII ion is located on a crystallographic inversion center. The asymmetric unit contains one 4-methyl­benzoate anion, one nicotinamide (NA) ligand and one coordinated water mol­ecule. The four O atoms in the equatorial plane around the MnII ion form a slightly distorted square-planar arrangement, while the slightly distorted octa­hedral coordination is completed by the two pyridine N atoms of the NA ligands in the axial positions. The dihedral angle between the carboxyl­ate group and the attached benzene ring is 9.01 (7)°, while the pyridine and benzene rings are oriented at a dihedral angle of 42.44 (5)°. In the crystal structure, inter­molecular O—H⋯O, N—H⋯O and C—H⋯O hydrogen bonds, and O—H⋯π and C—H⋯π inter­actions link the mol­ecules into a two-dimensional network parallel to (001).
