Synthesis and spectroscopic studies of novel transition metal complexes with schiff base synthesized from 1,4-bis-(o-aminophenoxy)butane and salicyldehyde
摘要:
The new Co(II), Cu(II), Ni(II) and Zn(II) complexes of potentially N2O2 Schiff base ligand [N,N'-bis(salicyldehydene)-1,4-bis-(o-aminophenoxy)butane] (H2L) prepared from 1,4-bis-(o-aminophenoxy)butane and salicyldehyde in DMF. Microanalytical data, elemental analysis, magnetic measurements, H-l NMR, C-13 NMR, UV-visible and IR spectra as well as conductance measurements were used to confirm the structures. In all complexes, H2L behaves as a tetradentate.
