摘要：

The new quaternary oxysulfide, La20Ti11S44O6, crystallizes in the orthorhombic system, space group Pmmn (No. 59), Z = 2, a = 22.700(5) Angstrom, b = 14.381(3) Angstrom, c = 10.454(2) Angstrom. The structure was determined from a single-crystal X-ray diffraction study and led to conventional R factors, R = 0.051, R(w) = 0.059 for 3264 reflections (I > 4 sigma(I)). Lanthanum atoms are engaged in mono-, bi-, or tricapped trigonal prismatic polyhedra; titanium atoms are all octahedrally coordinated. Rutile-like chains made of edge-sharing Ti(S,O)(6) octahedra are located in tunnels parallel to the (b) over right arrow and (c) over right arrow directions. (C) 1995 Academic Press,Inc.
