Schiff Base Copper(II) and Zinc(II) Complexes: Synthesis, Structures, and Antimicrobial Activities
摘要:
A new halo-substituted Schiff base ligand 2-bromo-6-[(2-ethylaminoethylimino)methyl]phenol (HL) and its copper(II) and zinc(II) complexes [Cu2L2(mu(1,1)-NCS)(2)] (1) and [ZnCl2(HL)] (2) (HL is the zwitterionic form of the Schiff base ligand) have been prepared and characterized by elemental analyses, IR, and single-crystal X-ray crystallographic determination. The crystal of (1) is monoclinic: space group P2(1)/c, a = 10.909(1), b = 13.976(1), c = 10.161(1) angstrom, beta = 111.471(2)degrees, V = 1441.7(2) angstrom(3), Z = 2. The crystal of (2) is monoclinic: space group P2(1)/n, a = 7.2682(4), b = 20.195(1), c = 10.8447(6) angstrom, beta = 106.420(2)degrees, V = 1526.9(2) angstrom(3), Z = 4. The Cu atoms in the copper complex are in square pyramidal coordination. The Zn atom in the zinc complex is in tetrahedral coordination. The effect of the complexes on the antimicrobial activity against Staphylococcus aureus, Escherichia coli, and Candida albicans were studied.

Two new Schiff base ligands, 2-bromo-6-[(3-cyclohexylami nopropylimino)methyl]phenol (L-1) and 2-bromo-6-[(2-ethylami noethylimino)methyl]phenol (L-2), and their mononuclear nickel (II) complexes, 2[Ni(L-1)(2)(N-3)(2)]center dot EtOH center dot H2O (1) and [Ni(L-2)(2)(NCS)(2)] (2), have been prepared and characterized on the basis of elemental analyses, IR spectra, and single-crystal X-ray diffraction. The complexes are mononuclear. The preliminary biological tests show that the complexes have effective antibacterial activity. Supplemental materials are available for this article.
