カラムからなる複合結晶Sr_xTiS_3(x=1.1-1.2)の結晶構造 Crystal Structures of Columnar Composite Crystals Sr_xTiS_3 (x=1.1-1.2)
The exsistence of incommensurate composite crystals Sr<I><SUB>x</SUB></I>TiS<SUB>3</SUB> (<I>x</I>=1.1-1.2) was revealed, and the powder X-ray diffraction patterns were assigned using a trigonal symmetry and four integers. The crystal structure was analyzed on the basis of the four-dimensional superspace group P<SUP>R.3m</SUP><SUB>1s</SUB> using powder X-ray diffraction data and the Rietveld analysis process. The crystals are composed of columns of face-shared polyhedra, (TiS6/2) ∞, and rows of Sr, and both are parallel to the c-axis.
