Abstract

The new molybdenum(Ⅴ)-triethylenetetraamine complexes such as Trien$H_4(MoOCl_5)_2,\;(MoOCl_3)_2$(trien), and$Mo_2O_4Cl_2$ (trien) have been prepared, and the chemical, magnetic and spectroscopic properties of the complexes have been investigated. Trien$H_4(MoOCl_5)_2has been isolated as green crystal and from this salt the nonelectrolytic and paramagnetic complexes,$(MoOCl_3)_2$ (trien) have been prepared by evolution of hydrogen chloride in anhydrous ethanol. Hydrolysis of triethylenetetraammonium oxopentachloromolybdate(V) yielded the nonelectrolytic and dismagnetic complex, $Mo_2O_4Cl_2$(trien) as brown solid.

Trien$H_4(MoOCl_5)_2,\;(MoOCl_3)_2$(trien) 및 $Mo_2O_4Cl_2$(trien)등의 몰리브덴(V)의 트리에틸렌 테트라아민착물을 합성하고 이들 착물의 화학적, 자기적 및 분광학적 성질을 조사하였다. Trien$H_4(MoOCl_5)_2$는 파란색 결정으로 무수에탄올에서 탈염화수소시켜 비전해질인 상자성착물 $H_4(MoOCl_5)_2$(trien)을 얻고 또한 $H_4(MoOCl_5)_2$Trien를 가수분해시켜 갈색의 비전해질인 반자성착물$Mo-2O_4Cl_2$(trien)을 얻었다.
