Abstract: Some copper(II) complexes having general formula, [(μ-Cl)2Cu2-(sb)}2] 1, 2 and [Cu{η-(sb)}2] 3,4, [where sbH =Schiff base, (salicylidene-2-aminophenol (saphH) for 1, 3 and salicylidene-3-nitro-1-aminobenzene (snabH) for 2, 4 have been synthesized by the interactions of anhydrous CuCl2 with sodium salt of corresponding Schiff bases in different molar ratio(s) using THF and benzene as reaction medium. The complexes 1, 2 have been further treated with various sodium salts of phenol, hydroxobenzaldehyde and aluminiumtetraisopropoxide to produce some novel mixed ligand complexes of the types, [(μ-Oar)2Cu22-(sb)}2] 5,6, [(η2-OBa) Cu{η2-(sb)}] 7, 8 and [(μ-OPri)2Al(OPri)2}Cu{η2-(sb)}] 9, 10. All these derivatives have been characterised by elemental analysis, spectral (IR, UV-visible and ESR), magnetic susceptibility measurements and FAB-mass studies. On the basis of these results, a dimeric square planar geometry around copper(II) for the complexes 1, 2, 5 and 6 has been suggested.
