Özet

The mixed-ligand m-hydroxybenzoate complexes of Co(II), Ni(II), Cu(II) and Zn(II) with nicotinamide were synthesized and characterized. The chemical, FT IR and UV-vis spectrophotometric, thermal and mass spectral analyses, magnetic susceptibility measurements revealed that the compounds contain two water molecules, two m-hydroxybenzoate (m-hba) and two nicotinamide (na) ligands per formula unit. m-Hydroxybenzoate and nicotinamide ligands bind to the metal atoms monodentately through their acidic oxygen and pyridinic nitrogen atoms, respectively. The thermal decomposition pathways and the stability of the complexes are interpreted in the terms of the structural data.
