四金化硅

四金化矽是一种无机化合物，化学式为SiAu4，在这种化合物中，金作为电子的接受体，显-1价。四金化硅作为金代矽烷的一种已被分离出来。Kiran, Xi Li, Hua-Jin Zhai, et al. [SiAu4]: Aurosilane. Angewandte Chemie, 2004. DOI: 10.1002/anie.200353602其晶胞参数为a=5.658, c=5.605 A。SiAu4的LUMO和四个Si—Au成键轨道均与SiH4相似。D.P. WOODRUFF. Atomic Clusters: From Gas Phase to Deposited . 5.
