Abstract
Two new dimeric oxovanadium(V) complexes, [VO2L1]2 (1) and [VO2L2]2 (2), where L1 and L2 are the monoanionic form of 2-{1-[2-(2-hydroxyethylamino)ethylimino]ethyl}phenol (HL1) and 2-[1-(2-ethylaminoethylimino)ethyl]phenol (HL2), respectively, have been synthesized and characterized by elemental analysis, FT-IR spectra, and single-crystal X-ray determination. The crystal of complex (1) is orthorhombic: space group Pbca, a = 9.284(1), b = 12.733(2), c = 21.626(3) Å, V = 2556.5(7) Å3, Z = 4. The crystal of complex (2) is orthorhombic: space group Pbca, a = 9.618(2), b = 12.416(3), c = 21.370(3) Å, V = 2552.0(9) Å3, Z = 4. The V···V distances are 3.138(1) Å in complex (1) and 3.141(1) Å in complex (2). The V atoms in the complexes are octahedrally coordinated. The antimicrobial activity of the free Schiff bases and the complexes were studied. The complexes have potential activities against Staphylococcus aureus, Escherichia coli, and Candida albicans.
