Three new mercury rare earth sulfides have been synthesized by heating a mixture of thesesquisulfide of rare earth and cinnabar at 800℃ for 25 h in an evacuated(10~(-4) Torr)sealed quartztube.Their general formula,Ln_4HgS_7(Ln=Tm,Yb and Lu),was determined by chemical anal-ysis.These sulfides are tetragonal.Lattice parameters for Ln=Tm,
Three new mercury rare earth sulfides have been synthesized by heating a mixture of thesesquisulfide of rare earth and cinnabar at 800 ° C for 25 h in an evacuated (10 -4 Torr) sealed quartz tube. Their general formula, Ln_4HgS_7 (Ln = Tm , Yb and Lu), was determined by chemical anal-ysis. These sulfides are tetragonal. Lattice parameters for Ln = Tm,
