Abstract: | Preparation and Crystal Structure of Cu2SrSnS4 Cu2SrSnS4 was prepared from a mixture of the three binary sulfides at 620-700° C. The structure analyses by single crystal X-ray investigations yields a trigonal C-symmetrie for the unit of the structure with a = 6.290 and c = 15.578 Å and three formula units. Space group: C –P31 (No. 144). Copper and tin have tetrahedral surrounding of S2?. The neighbourhood of Sr2+ has the shape of a deformed archimedic antiprisma. |
