【摘要】 本文考察了新合成的两个二元羧酸取代的三核钼衍生物Mo3 S4 (DTP) 3 (phthalate) (Py) (A) (DTP =diethyldithiophosphate,[S2 P(OEt) 2 ]-)和Mo3 S4 (DTP) 3 (malonate) (Py) (B)的红外吸收光谱 ,对Mo—S键及配体的主要吸收峰进行了归属和讨论 ,并与化合物Mo3 S4 (DTP) 4(Py) (C)的谱图进行了比较。结果表明 ,通过对这类复杂化合物红外特征振动分析可以获得较为丰富的结构信息。更多还原

【Abstract】 Two trinuclear molybdenum cluster compounds co or dinated by binary carboxylates compounds Mo 3S 4(DTP) 3(phth alate)(Py)(A) and Mo 3S 4(DTP) 3(malonate)(P y)(B) have been synthesized.IR absorption peaks of Mo 3S 4 core and the liga nds are assigned with reference to those of Mo 3S 4(DTP) 4(Py) (C).The assignment of stretching vibrations of carboxylate (COO--) for both (A) and (B) reveals much information corresponding to their molecular structure s.更多还原
