Materials Data on Ti5S8 by Materials Project
Ti5S8 crystallizes in the monoclinic Pm space group. The structure is two-dimensional and consists of three Ti5S8 sheets oriented in the (0, 0, 1) direction. there are five inequivalent Ti+3.20+ sites. In the first Ti+3.20+ site, Ti+3.20+ is bonded to six S2- atoms to form a mixture of face, edge, and corner-sharing TiS6 octahedra. The corner-sharing octahedral tilt angles are 47°. There are a spread of Ti–S bond distances ranging from 2.42–2.53 Å. In the second Ti+3.20+ site, Ti+3.20+ is bonded to six S2- atoms to form a mixture of edge and corner-sharing TiS6 octahedra. The corner-sharing octahedral tilt angles are 47°. There are a spread of Ti–S bond distances ranging from 2.39–2.57 Å. In the third Ti+3.20+ site, Ti+3.20+ is bonded to six S2- atoms to form a mixture of face, edge, and corner-sharing TiS6 octahedra. The corner-sharing octahedra tilt angles range from 7–47°. There are a spread of Ti–S bond distances ranging from 2.37–2.56 Å. In the fourth Ti+3.20+ site, Ti+3.20+ is bonded to six S2- atoms to form edge-sharing TiS6 octahedra. There are a spread of Ti–S bond distances ranging from 2.42–2.50 Å. In the fifth Ti+3.20+ site, Ti+3.20+ is bonded to six S2- atoms to form a mixture of edge and corner-sharing TiS6 octahedra. The corner-sharing octahedral tilt angles are 7°. There are a spread of Ti–S bond distances ranging from 2.41–2.48 Å. There are eight inequivalent S2- sites. In the first S2- site, S2- is bonded in a distorted T-shaped geometry to three Ti+3.20+ atoms. In the second S2- site, S2- is bonded in a distorted T-shaped geometry to three Ti+3.20+ atoms. In the third S2- site, S2- is bonded in a rectangular see-saw-like geometry to four Ti+3.20+ atoms. In the fourth S2- site, S2- is bonded to five Ti+3.20+ atoms to form a mixture of edge and corner-sharing STi5 square pyramids. In the fifth S2- site, S2- is bonded in a distorted T-shaped geometry to three Ti+3.20+ atoms. In the sixth S2- site, S2- is bonded in a distorted T-shaped geometry to three Ti+3.20+ atoms. In the seventh S2- site, S2- is bonded to five Ti+3.20+ atoms to form a mixture of distorted edge and corner-sharing STi5 trigonal bipyramids. In the eighth S2- site, S2- is bonded in a rectangular see-saw-like geometry to four Ti+3.20+ atoms.
