Synthetic, structural and biological properties of binuclear complexes with some Schiff bases

The complexes of Co(II), Ni(II) and Cu(II) with N,N′-bis-[5-X- salicylidene]-4,4′-diaminodibenzyl, abbreviated as H2-XSalPDADB (X = -H, -CH3, -Br) have been synthesized and investigated by elemental analysis, electrical conductance, magnetic, spectral and thermal studies. The molar conductivity data indicate that the complexes are non-electrolytes. Analytical data support 1:1 (M:L) stoichiometry. The reflectance spectra along with the magnetic data suggest pseudo-tetrahedral geometry for the complexes. The Schiff bases function as tetradentate ligands coordinating through ON-NO donor system. Substitution in the phenyl ring of the complexes produces shift in the azomethine ν(C=N) stretching vibrational frequency, which is related to the Hammett's substituent perameter (σ). The 1H-NMR data reveal that all Schiff bases exist in enol-iminic form. Various ESR parameters for copper complexes have been calculated. The compounds have been screened for their biological activities.

AZOMETHINE METAL-COMPLEXED PIGMENTS FROM THE BIBENZYL SERIES

A new series of Schiff bases derived from 4,4'-diamino- and 2,2'-diaminobibenzyl have been prepared and characterized.UV, IR and NMR spectra suggest that the ligands 7 and 8 formed by salicylaldehyde only exist in the enoliminic form, while the ligands 9
