Abstract: The reactions of the Schiff base H2salophen (H2salophen = N,N'-Bis(salicylidene)diaminobenzene), with Chloride copper (II) salt afforded the mononuclear complexes formulated respectively as [Cu(L)]4.16H2O (1). The compound has been studied and characterized by elemental analysis, IR and UV-Vis spectroscopies, molar conductivity, and room temperature magnetic measurements. The structure of the complex has been resolved by X-ray crystallography technique. The complex (1) crystallises in the monoclinic space group P21/c with the following unit cell parameters a = 11.7571(2) Å, b = 16.8082(2) Å, c = 36.5351(5) Å, β = 94.9540(10)°, V = 7192.94(18) Å3, Z = 16, Z' = 4, R1 = 0.0493.......
Keywords. Schiff base; 1,2-diaminobenzene; 2-hydroxy benzaldehyde; X-ray; Copper (II)
