Some vanadium(Ⅲ) complexes have been prepared by the reaction of VCl3·3MeCN with ligands and characterized by elemental analysis, 1H-NMR, infrared and UV-Visible spectroscopy. 3,5-lutidine(lutd), 8-hydroxyquinoline(oxine), 1,2-phenylenediamine(phda), ethylenediamine(en), and sym-diphenylethylenediamine(dpen) were chosen as coordinating ligands. ν(V-Cl) of lutidine complex occurs at 418 cm-1 and the other complexes (oxine, phda, en, dpen) occur at 337∼347 cm-1. The value of ν(V-Cl) indicates that the former complex has trigonal bipyramid structure and the latter complexes have octahedral structure. The ν(C≡N) of acetonitrile in oxine and phda complexes are characteristically shifted to about 70 cm-1 higher frequency compared with that of free ligand (2260 cm-1). The δ(C≡N) is also shifted to about 60 cm-1 higher frequency compared with that of free ligand (377 cm-1). Finally each vanadium(Ⅲ) complex showed the following formulation; [VCl3(lutd)2], [VCl(oxine)2MeCN]Cl2, [VCl(phda)2MeCN]Cl2, [VCl2(en)2]Cl, [VCl2(dpen)2]Cl.
