Syntheses, Characterization and Spectroscopic Studies on Schiff base Complexes of Diaminomaleonitrile

Wahengbam Bembee Devi, R. K. Bhubon Singh

Abstract: Three new Schiff base complexes viz, [Co(II)(bchbam)(H2O)] (1), [Ni(II)(bchbam)] (2) and [Cu(II)( bchbam)](H2O) (3), where bchbam = 2,3-bis(5-chloro-2-hydroxybenzylideneamino)maleonitrile, have been synthesized and characterized. The X-ray powder diffraction result shows the free ligand and complexes (1), (3) have monoclinic crystal system whereas the complex (2) was found to be triclinic in nature. Spectroscopic and analytical results suggest the tentative molecular structure of the complexes to be square planar and square pyramidal geometry where the ligand behaves as tetradentate N, O-donor ligand. A DNA binding study suggests the free ligand and its complexes were avid binders to Calf Thymus DNA (CT-DNA).
