A new compound 5CsBr.2SmBr3.22H2O is discovered and obtained in the system. X-ray powder diffraction, thermal analysis (TG and DTA) and polarization character of the new compound obtained from the system are investigated.Meanwhile, the synthetic mechanisms of compounds (CsSm2Br7, Cs3Sm2Br9, Cs3SmBr6 and Cs2SmBr5) are suggested on the basis of phase chemical relation of the system.展开更多
