在二甲胺基二硫代甲酸钠、氯化亚铁及四硫代钼酸铵的自兜反应体系中,以分步结晶法分离出MoFe_3S_4(Me_2NCS_2)_5·CH_2Cl_2及 MoFe_3S_4(Me_2NCS_2)_6·2CH_3CN 等单立方烷簇合物,并测定了后者的结构.它的分子含两个 Me_2NCS_2桥,并具有最高核心氧化态[MoFe_3S_4]~(6+).本文报道该化合物的结构特点,指出在自兜反应体系中,可能存在几种不同氧化态的单立方烷原子簇化合物.
MoFe 3 S 4 (Me_2NCS_2) _5 · CH_2Cl_2 and MoFe_3S_4 (Me_2NCS_2) _6 · 2CH_3CN were separated by the step crystallization method in the self-capping reaction system of sodium dimethyldithiocarbamate, ferrous chloride and ammonium tetrathiomolybdate And its structure was determined.The molecule contains two Me_2NCS_2 bridges and has the highest core oxidation state of [MoFe_3S_4] ~ (6+). The structural characteristics of this compound are reported in In the self-bail reaction system, there may be several mononuclear alkane cluster compounds with different oxidation states.
