Some novel complexes of Co(II) with 2-(o-hydroxybenzophenoneimino) benzohydroxamic acid in presence of bases like water, ammonia, pyridine, phenyl isocyanide, quinoline and -picoline have been synthesised and characterised on the basis of elemental analyses, molar mass determination, molar conductance and magnetic susceptibility measurements, UV-visible and IR spectroscopic investigations. The complexes have been formulated as [Co(L) (B)3] where, L=dideprotonated 2-(o-hydroxybenzophenoneimino) benzohydroxamic acid(LH2) and B=H2O, NH3, pyridine, phenyl isocyanide, quinoline and -picoline. Here, the ligand behaves as dianionic tridentate ligand. The complexes have been found to be paramagnetic and non-electrolytic in nature. All the complexes are found to have octahedral geometry as indicated by the values of magnetic moments and the positions of U.V.-visible spectral bands.

Hydroxamic acid, chelating ligand, spectral investigation, molar conductance etc.
