Diaquabis(4-bromobenzoato-O)bis(nicotinamide-N¹)cobalt(II)

T. Hökelek, N. Çaylak and H. Necefoglu

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-HO and N-HO hydrogen bonds link the molecules into two-dimensional sheets.
