Materials Data on Cs2TiS3 by Materials Project
Cs2TiS3 crystallizes in the orthorhombic Cmc2_1 space group. The structure is three-dimensional. Cs1+ is bonded in a 7-coordinate geometry to seven S2- atoms. There are a spread of Cs–S bond distances ranging from 3.52–3.86 Å. Ti4+ is bonded to five S2- atoms to form distorted edge-sharing TiS5 trigonal bipyramids. There are one shorter (2.24 Å) and four longer (2.42 Å) Ti–S bond lengths. There are two inequivalent S2- sites. In the first S2- site, S2- is bonded in a 2-coordinate geometry to four equivalent Cs1+ and two equivalent Ti4+ atoms. In the second S2- site, S2- is bonded in a distorted single-bond geometry to six equivalent Cs1+ and one Ti4+ atom.
