Abstract
The reactions of the Schiff base 2,2’-[1,1’-(ethane-1,2-diyl)bis(nitriloethylidyne)]diphenol (H2L), which was synthesised by condensation of 2-hydroxyacetophenone and ethylenediamine in the 2:1 ratio, with acetate copper (II) Salt, afforded a new mononuclear complex formulated as [Cu(L)].(H2O)0.5. The ligand and the complex have been characterized by elemental analysis, FTIR, UV-Vis and 1H and 13C NMR spectroscopies. The characterization of the copper complex was completed by molar conductivity and room temperature magnetic measurements. The structure of the complex has been resolved by X-ray crystallography technic. The mononuclear copper (II) complex crystallises in the monoclinic space group C2/c with the following unit cell parameters a = 26.131(6) Å, b = 7.293(5) Å, c = 17.256(4) Å, β = 106.10(5)°, V = 3160(2) Å3, Z = 4, R1 = 0.077 and wR2 = 0.145. In the structure of the complex the ligand acts in tetradentate fashion and the coordination environment of the copper atom is best described as distorted square planar geometry.
