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).
