摘要

The purpose of this work is synthesis of novel Schiff base ligand, 2-((1H-benzo[d]imidazol-4-ylimino)methyl)phenol and its metal complexes from 1H-benzo[d] imidazole-4-amine and 2-hydroxy benzaldehyde. Nickel and Copper being essential trace elements have given considerable attention for the synthesis of metal complexes. They have been characterized by elemental analysis and spectral techniques like IR, 1HNMR and mass spectrometry. The spectral studies of the complexes reveal that the ligand has coordination through the O and N atoms of the ligand. Cell dimensions a(13.554540 Å), b(9.496137 Å), c(4.471746 Å), α(90.000), β(90.000) and γ(90.000) for Nickel complex and a(22.094890 Å), b(8.983012 Å), c(8.483077 Å), α(90.000), β(90.000) and γ(90.000) for Copper complex are in good agreement with Orthorhombic crystal systems for both. The molecular structure of the complexes has been optimized by MM2 calculation and suggested tetrahedral geometry with sp3 hybridisation of copper and square planar geometry with dsp2 hybridization of nickel complex respectively.
