1,1-di(Nsalicyloylhydrazonoethyl)ferrocene and its coordination compounds with transition metals

1,1'-Di(N-salicyloylhydrazonoethyl)ferrocene and its coordination compounds with transition metals, ML.nH2O M = Mn(II), Co(II), Cu(II), Cd(II), Zn(II) and Ni(II)] are synthesized and characterized by elemental anal., UV-vis, IR, 1H NMR, TG-DTA and molar conductance. The ligand coordinates metals through azomethine nitrogen atom and amide oxygen atom in enol form, NI(II) coordination compound contains a mol. DMF. In all coordination compounds ligand reacts with metal in 1:1 ratio and these coordination compounds are weak electrolytes in DMF. Most coordination compounds are more thermostable than the ligand.
