텅스텐(Ⅴ)-티오시안산 置換 피리딘錯物의 合成과 그 性質 = Preparation and Characterization of Substituted Pyridine Complexes of Thiocyanato-tungsten(Ⅴ)

다국어 초록 (Multilingual Abstract)

Two types of thiocyanato-tungsten(Ⅴ)-substituted pyridine complexes, such as WO NCS)₃(x-py)₂(x-py)(x-py were pyridine, 2-amino pyridine, 3.5- lutidine and 2- amino-4-picoline) and WO(OH)(NCS)₂(x-py)(x-py were pyridine, α-picoline, 2-amino pyridine and 4-acetylpridine) have been prepared.
The physical properties such as conductances, magnetic moment and spectroscopy of the thiocyanato-tungsten(Ⅴ)-substituted pyridine complexes have been studied. From the results the complexes are paramagnetism and none-ionic complexes. It is found that the these tungsten(Ⅴ) complexes are insoluble in water, alcohol, acetone or dimethyl formamide, etc. and unstable in air atomosphere.
From the assignment of the infrared spectra of the thiocyanato-tungsten(Ⅴ)-substituted pyridine complexes, it was shown that tungsten was combined with nitrogen of thiocyanate ligand.
