trans-Diaquabis(3-hydroxybenzoato-O)bis-(nicotinamide-N 1)cobalt(II)

The title compound, [Co(C7H5O3)2(C6H 6N2O)2(H2O)2], is a monomeric and centrosymmetric cobalt complex. It contains two 3-hydroxybenzoate anions, two nicotinamide (NA) molecules and two water molecules as ligands. Each ligand is monodentate. The two nearest carboxylate O atoms and the two water O atoms form a slightly distorted square-planar arrangement around the Co atom [with distances of 2.099 (3) and 2.132 (3) A, respectively], while the distorted octahedral coordination is completed by the pyridine N atoms of the NA ligands at a distance of 2.139 (4) A. There is an intramolecular hydrogen bond between the nicotinamide N and O atoms [N...O 2.228 (6) A], and the hydroxybenzoate and water O atoms form inter- [2.662 (5) A] and intramolecular [2.586 (5) A] hydrogen bonds, respectively, with the non-coordinated O atom of the carboxylate group.

Synthesis and characterization of bis(nicotinamide) m-hydroxybenzoate complexes of Co(II), Ni(II), Cu(II), and Zn(II)

Mixed-ligand m-hydroxybenzoate complexes of Co(II), Ni(II), Cu(II), and Zn(II) with nicotinamide were synthesized and characterized by elemental analysis, FT-IR spectrometry, solid state UV-vis spectrometry, and magnetic susceptibility measurements. The thermal behavior of the complexes was studied by simultaneous TG-DTA methods in static air atmosphere. The infrared spectral characteristics of the complexes are discussed and the mass spectra data are recorded. The complexes contain two water molecules, two m-hydroxybenzoato (m-hba), and two nicotinamide (na) ligands per formula unit. In these complexes, the m-hydroxybenzoate and nicotinamide behave as a monodentate ligand through acidic oxygen and nitrogen of the pyridine ring. The decomposition pathways and the stability of the complexes are interpreted in terms of the structural data. The final decomposition products were found to be the respective metal oxides.
