ROOM TEMPERATURE SYNTHESIS IN LIQUID AMMONIA OF TIN SULFIDE

Reaction of elemental tin with sulfur in liquid ammonia at room temperature affords an intimate mixture of X-ray amorphous metal sulfides (SnS, SnS2) and a trace of tin metal.Thermolysis of this material at 300-350°C for 2 hrs.produced crystalline tin (II) sulfide (SnS -Herzenbergite).Products were characterised by elemental analysis, FT-IR and Raman spectroscopy, 119 Sn NMR, X-ray powder diffraction, Scanning Electron Microscopy (SEM) and Energy Dispersive X-ray Analysis (EDXA).
