Investigation of the Y2S3-PbS-SnS2 System at 770 K

The interactions between the components in the Y2S3-PbS-SnS2 system at 770 K were determined using X-ray powder diffraction. The existence of the Y2PbS4 (unknown structure) compound in the Y2S3-PbS section and the PbSnS3 (PbSnS3 structure type, space group Pnma) compound in the PbS-SnS2 section was confirmed. No compounds were observed in the Y2S3-SnS2 section. The crystal structure of new quaternary Y2Pb3Sn3S12 (space group Pmc21, a = 0.39021(2) nm, b = 2.01003(8) nm, c = 1.15169(5) nm, RI = 0.0872) compound in the Y2S3-PbS-SnS2 system at 770 K was investigated using X-ray powder diffraction.
