The Schiff base ligand N,N'-bis(3-ethoxy-2-hydroxybenzylidene)ethylenediamine (H2L) reacting with vanadyl acetylacetonate and zinc chloride, respectively, in methanol gave the complexes [VOL]center dot H2O (I) and [ZnL(OH2)] (II). Both complexes were characterized by elemental analyses and IR spectroscopic method in the solid state. Single crystal X-ray analysis was performed, which reveals that both of them are mononuclear complexes. Complex I crystallizes in the monoclinic space group P2(1)/c with unit cell dimensions a = 9.4387(7), b = 16.996(1), c = 12.758(1) angstrom, beta = 98.269(2)degrees, V = 2025.4(3) angstrom(3), Z = 4, R-1 = 0.0365, and wR(2) = 0.0946. Complex II crystallizes in the tetragonal space group P (42) over bar (1)m with unit cell dimensions a = b = 22.0489(8), c = 4.9846(4) angstrom, V = 2423.3(2) angstrom(3), Z = 4, R-1 = 0.0890, and wR(2) = 0.2278. The V atom in I and the Zn atom in II are in square pyramidal coordination. Anbacterial activities of the Schiff base ligand and the complexes have been studied on the strains B. subtilis, E. coli and S. aureus.
