A pro-chiral Schiff base ligand (HL) was synthesized by the reaction of 2-amino-2-ethyl-1,3-propanediol and pyridine-2-carbaldehyde in methanol. The reaction of HL with CuCl·2HO and CuBr in methanol gave neutral mononuclear Cu(II) complexes with general formula of [Cu(HL)Cl] (1) and [Cu(HL)Br] (2), respectively. By slow evaporation of the methanolic solutions of 1 and 2, their enantiomers were isolated in crystalline format.
