Di-μ- nicotinamide-k ² N ¹:O;k ² O:N ¹-bis-[aqua-bis-(4-bromo-benzoato)-kO;k ² O,O′-manganese(II)]

In the centrosymmetric dinuclear title compound, [Mn ₂(C ₇H ₄BrO ₂) ₄(C ₆H ₆N ₂O) ₂(H ₂O) 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 molecule 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 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.
