Structure of tin(II) tin(IV) trisulphide, a redetermination

Sn 2S 3 is orthorhombic with Pnma, a=8.878 (2), b=3.751 (1), c=14.020 (3) Aring, Z=4, Dm=4.87, Dx=4.75 Mg m -3, Mr=333.6, mu(Mo Kalpha)=11.8 mm -1, and the final R=0.04 for 1335 observed X-ray data. The crystal structure was redetermined using a crystal of improved quality and a diffractometer and applying corrections for absorption and extinction. The results of the previous determination with film data by Mootz & Puhl (see ibid., vol.23, p.471-476, 1967) were confirmed, but a higher accuracy and more reliable anisotropic thermal parameters were achieved.
