The complexes were characterized by elemental analysis, UV-Vis and infrared spectroscopies, as well as H-1, C-13, and V-51 NMR. The crystal and molecular structure of 1, the first binuclear alkoxo-bridged oxoalkoxo vanadium(V) complex, and 2 were determined by X-ray diffraction from single crystals. Complex 1 is a dimer with distorted octahedral geometry, while 2 is monomeric with distorted octahedral geometry. H-1 NMR data revealed that alkoxy signal of 1-3 (OCH3, OCH2R and OCHR2) are deshielded with the trend 5.68, 6.14, and 6.84 ppm, respectively. V-51 NMR data of these complexes are in the range of reported chemical shifts of complexes of the type VO6-nNn (n = 0-2).
