Beschreibung
Zusammenfassung:	The crystal structure of the R2PbS4 (R=Yb and Lu) compounds (space group Pnma, Pearson symbol oP28, a=1.1899(2)nm, b=0.39015(8)nm, c=1.4127(2)nm, R1=0.0349 for Yb2PbS4 and a=1.1919(2)nm, b=0.38890(8)nm, c=1.4103(3)nm, R1=0.0343 for Lu2PbS4) was investigated by means of X-ray single crystal diffraction. The R atoms are surrounded by octahedra, the Pb atoms by trigonal prisms with one additional atom.
