                                    Two new dimeric oxovanadium(V) complexes, [VO2L1](2) center dot 2H(2)O (I) and [VO2L2](2) (II), where L-1 and L-2 are the monoanionic form of 5-methoxy-2-[(2-methylaminoethylimino)methyl]phenol (HL1) and 5-diethylamino-2-[(2-methylaminoethylimino)methyl]phenol (HL2), respectively, have been synthesized and characterized by elemental analysis, FT-IR spectra, and single crystal X-ray determination. The crystal of I is monoclinic: space group P2(1), a = 6.858(2), b = 16.630(3), c = 12.306(2) , beta = 103.985(2)A degrees, V = 1361.9(5) (3), Z = 2. The crystal of II is triclinic: space group , a = 7.378(2), b = 8.838(2), c = 13.312(3) , alpha = 102.576(2)A degrees, beta = 92.044(2)A degrees, gamma = 113.017(2)A degrees, V = 772.7(3) (3), Z = 2. The V...V distances are 3.140(1) in I and 3.254(1) in II. The V atoms in the complexes are in octahedral coordination. The effect of the complexes on the antimicrobial activity against Staphylococcus aureus, Escherichia coli, and Candida albicans was studied.
