本文用(NH_4)_2MoS_4与FeCl_3在乙二醇钠溶液反应,合成一种新型的含氧配位的Mo—Fe—S 原子簇化合物.经X光结构分析确定化学结构式为[(MoS_4)Fe(MoOS_4)][(C_4H_9)_4N]_3.并进行了红外光谱、紫外可见光谱的测定、穆斯堡尔谱测得的同质异能移位δ_m= 0.2263mms~(-1)、不对称四极矩劈裂 E_q=0.4527mms~(-1).该化合物具有在KBH_4条件下的乙炔还原为乙烯的活性。
In this paper, a novel oxygen-coordinated Mo-Fe-S cluster has been synthesized by the reaction of (NH_4) _2MoS_4 with FeCl_3 in sodium glycolate solution. The chemical structure of [MoS_4] Fe MoOS_4)] [(C_4H_9) _4N] _3. The infrared spectra and UV-Vis spectra were measured. The isomorphous displacements δ_m = 0.2263mms -1, The polar moment splitting E_q = 0.4527mms ~ (-1) This compound has the activity of reducing acetylene to ethylene under KBH_4 condition.
