摘要

AbstractIsothermal section of the Er2S3–La2S3–GeS2system at 770?K was investigated. The phase boundaries of the solid solution La4–4xR4xGe3S12(x?=?0–0.75, R – Tb, Dy, Ho and Er) were determined, and their structure was investigated by single crystal and powder X-ray diffraction. The existence of new quaternary compound Er2.34La0.66Ge1.28S7was established and its crystal structure was determined by X-ray single crystal diffraction (space groupР63, Pearson symbolhР24–1.44,a?=?0.96934(3) nm,c?=?0.58680(2) nm,R1?=?0.0220).Highlights?Isothermal section of the Er2S3–La2S3–GeS2system was investigated.?The crystal structure of La4–4xR4xGe3S12alloys (x?=?0–0.75, R – Tb, Dy, Ho and Er) was investigated.?The crystal structure of a new quaternary compound Er2.34La0.66Ge1.28S7was determined.]]>
