The influence of axial substituents on Cosingle bondC bond of organocobaloximes: Synthesis, structure and characterization

Three new cobaloximes (ClCH2Co(dpgH)2Y (Y = pyridine, water, N-methylimidazole, dpgH = diphenylglyoximate)) have been synthesized and characterized by elemental analysis and spectral studies. The molecular structures of ClCo(dpgH)2Py and ClCH2Co(dpgH)2N-methylimidazole are described. In the packing diagram of ClCH2Co(dpgH)2N-methylimidazole, molecules are bonded through CH–π interaction with the range of distances of 2.798–3.067 Å. The axial substituents, pyridine and N-methylimidazole affect the properties of the Co center.
