摘要：
The title compound, Sm3 (SiO4),2Cl, crystallizes in orthorhombic system, space group Pnma, with cell dimensions a= 7. 023 (2), b= 18. 022 (4), c= 6. 282(3) A, V= 795, 1(4) A3, Z=4, D.=5- 60 g/cm3, M.=670. 67, F(000) =1180, μ= 226. 1 cm-1. The final R= 0. 069, Rw = 0. 080 for 1370 observed reflections with I≥3. 0δ(I). Independent Sm(1)O6Cl2 and Sm(2)O7Cl polyhedra are connected throughshared-edge with each other along a direction, but both linked by sharing a face O2Cl toform a three-dimensional network structure.
