摘      要：The structure of AREI_3 is reported in this *** crystal structures,which include AREI_3(A=K,Rb,Cs;RE=Sm,Eu,Yb,Tm) were determined by X-ray powder diffraction method,Gui- nier technique was ***_3 was investigated by electron microscopy to confirm the polytype of AREI_3(SrCeO_3-type,Pmmm) observed in the X-ray diffraction experiments. The values as a function of structure type show that the structure of AREI_3 are different from that of other halides of AREX_3(X=F,Cl,Br)
