Di-μ-nicotinamide-κN:O;κO:N-bis-[aqua-bis-(4-bromo-benzoato)-κO;κO,O'-manganese(II)].

In the centrosymmetric dinuclear title compound, [Mn(2)(C(7)H(4)BrO(2))(4)(C(6)H(6)N(2)O)(2)(H(2)O)(2)], the Mn(II) atom is coordinated by one N atom from one bridging nicotinamide ligand and one O atom from another symmetry-related bridging nicotinamide ligand, three O atoms from two 4-bromo-benzoate ligands and one water mol-ecule in a distorted octa-hedral geometry. The dihedral angles between the carboxyl-ate groups and the adjacent benzene rings are 10.89 (16) and 8.4 (2)°, while the benzene rings are oriented at a dihedral angle of 6.09 (13)°. Inter-molecular O-H⋯O, N-H⋯O and weak C-H⋯O hydrogen bonds link the mol-ecules into a three-dimensional network. π-π inter-actions, indicated by short centroid-centroid distances [3.845 (2) Å between the benzene rings, 3.650 (2) Å between the pyridine rings and 3.700 (3) Å between the benzene and pyridine rings] further stabilize the structure.
