Abstract: The title Mn^II 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-HO hydrogen bonds link the molecules into infinite chains.
