Özet
In the centrosymmetric dinuclear title compound, [Mn-2(C7H4BrO2)(4)(C6H6N2O)(2)(H2O)(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)degrees, while the benzene rings are oriented at a dihedral angle of 6.09 (13)degrees. Intermolecular O-H center dot center dot center dot O, N-H center dot center dot center dot O and weak C-H center dot center dot center dot O hydrogen bonds link the molecules into a three-dimensional network. pi-pi interactions, indicated by short centroid-centroid distances [3.845 (2) angstrom between the benzene rings, 3.650 (2) angstrom between the pyridine rings and 3.700 (3) angstrom between the benzene and pyridine rings] further stabilize the structure.
