Two new complexes [V(O)(sal-o-phdn)(H2O)] and [V(O)(sal-o-phdn)(C2H5OH)] (sal-o-phdn = N,N'-o-phenylenebis(salicylideneiminato)) have been synthesized and characterized by elemental and thermal analysis and electronic, infrared and Raman spectra. Both complexes are in the mononuclear forms where the Schiff base occupies the four equatorial positions and H2O or C2H5OH are axially coordinated to the vanadyl oxygen forming distorted octahedral with CS symmetry. The characteristic ni(V=O) vibrations for the mononuclears are observed at 978 and 981 cm-1 for the H2O and C2H5OH complexes, respectively. Full vibrational assignments for all observed bands are made. The vibrations of the coordinatedH2Oin [V(O)(sal-o-phdn)(H2O)] are observed at 3255, 1704, 829 and 645 cm-1 while those for the C2H5OH in [V(O)(sal-o-phdn)(C2H5OH)] are shown at 3620, 2950, 1386 and 860 cm-1.
