In this paper, we present about the synthesis and characterisation of some
complexes of Co(II) metal with Schiff base. The complexes of Cobalt(II) cation have been
prepared with Schiff base ligand, benzophenonesemicarbazone in the presence of bases
having nitrogen and oxygen atoms as their donor sites. The general formulae of the
complexes have been found to be [Co(L)2(B)2] where L = ligand and B = bases. On the
characterisation of the ligand and the complexes by usual physico-chemical methods, all
the complexes have been found to be mono-meric, non-electrolyte, paramagnetic and
octahedral in geometry.
