Synthesis and characterization of some nickel(II), cobalt(II), and zinc(II) complexes with Schiff bases derived from the reaction of isonitroso-p-chloroacetophenone and 1,2-diaminoethane with 1,4-diaminobutane
MetadataShow full item record
Two new Schiff bases have been synthesized by the condensation of 1,2-diaminoethane (HL) and 1,4-diamino buthane (HL') with isonitroso-p-kloroasetafenon. The complexes of cobalt(II), nickel(II) and zinc(II) with HL and HL' were prepared. The ligands and their complexes were characterized by spectroscopic techniques.
