Abstract

The title MnII complex, [Mn(C7H4BrO2)2(C10H14N2O)2(H2O)2], is centrosymmetric. The mol­ecule contains two 2-bromo­benzoate (BB) and two diethyl­nicotinamide (DENA) ligands and two water mol­ecules, all ligands being monodentate. The four O atoms in the equatorial plane around the Mn atom form a slightly distorted square-planar arrangement, while the distorted octa­hedral coordination is completed by the two N atoms of the DENA ligands in the axial positions. The dihedral angle between the carboxyl group and the adjacent benzene ring is 79.95 (11)°, while the pyridine and benzene rings are oriented at a dihedral angle of 45.66 (6)°. In the crystal structure, inter­molecular O—H⋯O hydrogen bonds link the mol­ecules into infinite chains.
