Özet

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)degrees, while the pyridine and benzene rings are oriented at a dihedral angle of 45.66 (6)degrees. In the crystal structure, intermolecular O-H center dot center dot center dot O hydrogen bonds link the molecules into infinite chains.
