複雑多様な金属硫化物の結晶構造の解明 Complicated and Various Crystal Structures of Metal Sulfides.
Many kinds of complicated crystal structures have appeared in the transition metal sulfide system. Simulation by the matrix method could explain the diffuse scattering observed in nonstoichiometric titanium sulfides with stacking faults, in Ti<SUB>1.42</SUB>S<SUB>2</SUB> with short-range order of Ti vacancies, and in some channel-type composite crystals such as Ba<SUB>0.7</SUB>Cr<SUB>2</SUB>S<SUB>3.7</SUB> with two-directional disorder of positions of filling columns. Crystal structures of incommensurate layered composite crystal (PbS) <SUB>1.12</SUB>VS<SUB>2</SUB>, columnar composite crystals Ba<SUB>10/9</SUB>Fe<SUB>2</SUB>S<SUB>4</SUB> and Ba<SUB>9/8</SUB>Fe<SUB>2</SUB>S<SUB>4</SUB>, and incommensurate columnar composite crystals Sr<SUB>x</SUB>TiS<SUB>3</SUB> (x=1.1-1.2) were successfully analyzed based on the superspace group approach.
