[b] Preparation and Properties of Dinuclear Schiff Base Complexes of Co(II) and Ni (II) Via Inter-Complex Reaction[/b]
Journal Title: International Journal of Research in Chemistry and Environment (IJRCE) - Year 2013, Vol 3, Issue 2
Abstract
[i] Homo and hetero dinuclear Schiff base complexes were prepared by inter – complex reaction between Co (II) and Ni (II) complexes of o-vanillin and o-aminophenol. Elemental composition and thermal properties of the complexes were established. Structures of the complexes were elucidated by spectroscopic methods like infrared spectroscopy, UV-visible spectroscopy and mass spectrometry. The powder X-ray diffractogram indicated crystalline nature with tetragonal symmetry of the complexes. Magnetic properties of these complexes were extensively studied using Gouy balance and VSM at variable temperatures. Low temperature ferromagnetism was exhibited by homodinuclear complexes while the heterodinuclear complex displayed antiferromagnetic coupling at low temperatures. The structure with minimum energy was identified using molecular mechanical method.[/i]
