SYNTHESIS, CHARACTERISATION AND BIOLOGICAL SCREENING OF Cu (II) COMPLEXES OF PINCER LIGANDS
The ligands bis-(benzimidazolyl)pyridine (BBIP) and bis-(benzimidazolyl)benzene (BBIB) have been used to synthesize Copper(II) complexes [Cu(BBIP)2]Cl2 and [Cu(BBIB)2]Cl2 respectively. The complexes are characterized by analytical and spectral (FTIR, 1H NMR and electronic) techniques. IR spectra of complexes show that the tertiary nitrogens in the ligand are involved in the co-ordination to the me...
