Synthesis, characterization, and spectroscopic studies of novel transition metal complexes with N,N'-bis(salicylaldehydene)-1,4-bis(4-chloro-2-aminophenoxy)butane

The metal complexes of Co(II), Cu(II), Ni(II), and Zn(II) with novel quadridentate Schiff base derived from 1,4-bis(4-chloro-2-aminophenoxy)butane and salicylaldehyde have been synthesized in DMF. These complexes have been characterized by microanalytical data, elemental analysis, magnetic measurements. C, H-1 NMR, C-13 NMR, UV-vis and IR-spectra as well as conductance measurements were used to confirm the structures. On the basis of these observations it is suggested that these complexes exhibit the coordination number four.
