In this work, binuclear copper(II) complex of [L(N3)Cu(μN,N-N3)2CuL(N3)], 1-2 (L1 = N,N-dimethyl,N'-benzyl-ethylenediamine, L2 = N,N-diethylyl,N'-benzyl-ethylenediamine) ) has been synthesized and structurally characterized. X-ray crystallography study of the complex reveals that the copper (II) center has a distorted octahedral environment [1]. The experimental studies on the compounds have been accompanied computationally by the density functional theory (DFT) calculations. We utilized DFT/TDDFT calculations to obtain a theoretical support for absorption spectr and particular coordination geometry being adapted around the metal ion center.
