Synthesis and physicochemical studies of cobalt(II), nickel(II) and copper(II) complexes with various Schiff bases containing oxygen and nitrogen donor atoms

The complexes of cobalt(II), nickel(II) and copper(II) of the types [(sb)(2)M.2H(2)O] [where M = Co-II, Ni-II and Cu-II], [sbH = sapH, napH], [(CI)Cu(sb)] and [Cu(sb)(2)] [sb = sapH, smabH] have been prepared by using simple metathetic reactions. The structural characterization of the complexes, synthesized during the present course of investigations have been elucidated by elemental analysis (C, H, N, CI and Cu), IR, electronic spectral data, ESR, FAB-MS and magnetic studies. Thermogravimetric studies have also been carried out for some of the hydrated metal complexes.
