Materials Data on Ca(TiS2)4 by Materials Project
Abstract
Ca(TiS2)4 crystallizes in the trigonal R-3m space group. The structure is three-dimensional. Ca2+ is bonded to six equivalent S2- atoms to form distorted CaS6 octahedra that share corners with six equivalent TiS6 octahedra and edges with six equivalent TiS6 octahedra. The corner-sharing octahedral tilt angles are 8°. All Ca–S bond lengths are 2.80 Å. There are two inequivalent Ti+3.50+ sites. In the first Ti+3.50+ site, Ti+3.50+ is bonded to six S2- atoms to form TiS6 octahedra that share edges with two equivalent CaS6 octahedra and edges with six TiS6 octahedra. There are two shorter (2.44 Å) and four longer (2.47 Å) Ti–S bond lengths. In the second Ti+3.50+ site, Ti+3.50+ is bonded to six equivalent S2- atoms to form TiS6 octahedra that share corners with six equivalent CaS6 octahedra and edges with six equivalent TiS6 octahedra. The corner-sharing octahedral tilt angles are 8°. All Ti–S bond lengths are 2.44 Å. There are two inequivalent S2- sites. In the first S2- site, S2- is bonded in a rectangular see-saw-like geometry to one Ca2+ and three Ti+3.50+ atoms. In the second S2- site, S2- is bonded in a distorted T-shaped geometry to three equivalent Ti+3.50+ atoms.
