| ABSTRACT Copper complexes of N,N’,N’’,N’’’-Bis (benzil) azomethine Bis (1,2-ethylene diamine) and N,N’-Bis (benzil) azomethine 1,2-ethylene diamine have been prepared. These complexes have been studied using electron spin resonance and UV spectroscopic techniques. The electron spin resonance spectra of these complexes have been recorded in solution at room temperature and 77K. The spin Hamiltonian has been extracted to the atomic orbital coefficient in some of the molecular orbitals involved in bonding in these complexes. A structure-activity relationship is proposed on the basis of difference in magnetic parameters and consequent evaluation of molecular orbital coefficients K, β2, β12 and α2 under the assumption of an effective D4h symmetry, where the unpaired electron is in an antibonding orbital Ψ(B1g) compounded to the cupric ion dx2-y2 orbital and ligand σ-orbital | ||
