摘 要:<正> The structure of AREI3 is reported in this paper.Their crystal structures,which includeAREI3(A=K,Rb,Cs;RE=Sm,Eu,Yb,Tm) were determined by X-ray powder diffraction method,Gui-nier technique was used.CsEuI3 was investigated by electron microscopy to confirm the polytype ofAREI3(SrCeO3-type,Pmmm) observed in the X-ray diffraction experiments.The values as a function of structure type show that the structure of AREI3 are different from that ofother halides of AREX3(X=F,Cl,Br)
