Di-μ-nicotinamide-κ(2) N (1):O;κ(2) O:N (1)-bis­[aqua­bis­(4-bromo­benzoato)-κO;κ(2) O,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-bromo­benzoate ligands and one water mol­ecule in a distorted octa­hedral geometry. The dihedral angles between the carboxyl­ate 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)°. Inter­molecular O—H⋯O, N—H⋯O and weak C—H⋯O hydrogen bonds link the mol­ecules into a three-dimensional network. π–π inter­actions, 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.
