摘　　要：在二丙胺存在的条件下,Ge,S,Cd2+或Mn2+于150℃水热反应生成[(C3H7)2NH2]4(H2O)4Ge4S10单晶.单晶X射线衍射分析结果显示:该单晶为四方晶系,空间群I4(1)/amd;晶胞参数a=20.9275(4) ,c=11.3351(2) .此晶体由分隔的[Ge4S10]4-团簇构成,每个[Ge4S10]4-团簇周围被四个丙二胺分子所包围.The hydrothermal reaction of Ge, S, CdCl2 or MnCl2 at 150 ℃ in the presence of dipropylamine resulted in the production of crystals of 4(H2O)4Ge4S10, which were characterized by a single crystal Xray diffraction analysis . The crystals are composed of isolated 4- cluster, which is surrounded by four dipropylamine molecules.
