摘 要:The reaction of VCl3 with 4-(2, 4-dihydroxybenzaldimine) antipyrine (LH) in a l : 1 molar ratio results in formation of the general complex of [VOL(CI)OH]. The nature of bonding and stereochemistry of the complex was deduced from the elemental analysis, IR, UV-Vis, 1H and ^13C NMR spectroscopy. This complex has a coordination number five (square pyramidal) as known for many vanadyl complexes. The formation of the vanadyl ion (VO^2+) and the mode of bonding of the Schiff base through the oxygen of the pyrazol ring and the nitrogen of the azomethine group to the vanadyl ion were established by IR technique.
关 键 词:Schiff base Oxy-Vanadium(IV) complex ^1H and ^13C NMR.
