Diaquabis(4-methylbenzoatoκO)bis(nicotinamideκN ¹)manganese(II)

In the mononuclear title complex, [Mn(C₈H₇O ₂)₂(C₆H₆N₂O) ₂(H₂O)₂], the Mn^II 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 Mn^II ion form a slightly distorted squareplanar 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 mol-ecules into a twodimensional network parallel to (001).
