Abstract

Abstract: The title complex was prepared through the reaction of (Ph₃P)₂Ag(S₂CSR) (R=C₆H₅ or C₆H₂Prⁱ₃-2,4,6) formed by inserting of CS₂ into Ag-S bond of AgSR in the presence of Ph₃P with BrCH₂CH₂Br—P under mild conditions. The colorless block crystal belongs to rhombohedral system with the space group R3c, α=1.6421(2) nm, c=4.4075(9) nm, V=10.297(3) nm³, D_c=1.746 g·cm^-3, Z=6. The final R is 0.033 for 2244 independent reflections. The four silver atoms and four bromine atoms form a distorted cube, and each silver atom is tetrahedral coordinated by one P and three Br atoms.

Key words: insertion reaction of CS₂, silver cluster complex, crystal structure

摘要： 应用CS_２在AgS键中的单核插入产物(Ph₃P)₂Ag(S₂CSR)（R=C₆H₅或 C₆H₂Prⁱ₃-2，4，6）与1，2-二溴乙烷-异丙醇混合溶剂反应，生成一个中性四核银簇合物(Ph₃P)₄Ag₄Br₄，并利用X射线单晶衍射法测定其晶体结构。
