Özet
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.
