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. ¹H NMR, ¹³C 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. The text was submitted by the authors in English.
