BAILLY Laboratoire de Physique, Facultd des Sciences Pharmaceutiques et Biologiques de Paris-Sud, rue Jean-Baptiste Cldment, 92290 Chatenay Malabry, France (Refu le 21 fOvrier 1973, aeceptO le 23 mars 1973) The crystal structure of T14S3 has been determined by X-ray diffraction methods. The space group is P21/a and the cell constants are a=7.97, b=7.76, c= 13.03 ,h,, 7= 103.99o. The structure was solved by the heavy-atom method and refined by a least-squares program to a final R value of 0.08. One trivalent thallium atom is in tetrahedral coordination and forms isolated linkages with the three other T1+ which appear to be by electrostatic interaction. L'existence vraisemblable d'un compos6 T14S3 a 6t6 signal6e par Hahn & Klingler (1949). Plus r6cemment, d'apr~s Soulard & Tournoux (1971), il est apparu que le compos6 T14S3 puisse ~tre dimorphe: la forme fl se transformerait en forme c~ par broyage, mais la trans- formation
