Abstract

Component interaction at the Tl2Se-CdSe-SnSe2 section was investigated by x-ray diffraction and differential thermal analysis, and the phase diagram was constructed. The existence of a new quaternary compound Tl2CdSnSe4 with two polymorphous modifications was established. The crystal structure of the low-temperature modification of Tl2CdSnSe4 was determined. The compound crystallizes in space group I-42m, Pearson symbol tI16, a = 0.80490(6) nm, c = 0.68573(8) nm, RI = 0.0815.
