Abstract

The title complex, [Co(C7H4BrO2)(2)(C6H6N2O)(2)(H2O)(2)], is monomeric and centrosymmetric, and contains two water molecules, two 4-bromobenzoate (BB) anions and two nicotinamide (NA) ligands, all acting as monodentate ligands. The four nearest O atoms in the equatorial plane around the Co atom form a slightly distorted square-planar arrangement, while the distorted octahedral coordination is completed by the two NA N atoms in the axial positions. Intermolecular O - H center dot center dot center dot O and N - H center dot center dot center dot O hydrogen bonds link the molecules into two-dimensional sheets.
