Materials Data on Sm2TmS4 by Materials Project
TmSm2S4 crystallizes in the tetragonal I-42d space group. The structure is three-dimensional. Tm3+ is bonded in a 8-coordinate geometry to eight equivalent S2- atoms. There are four shorter (2.73 Å) and four longer (3.05 Å) Tm–S bond lengths. Sm+2.50+ is bonded to eight equivalent S2- atoms to form a mixture of distorted corner, edge, and face-sharing SmS8 hexagonal bipyramids. There are a spread of Sm–S bond distances ranging from 2.82–3.05 Å. S2- is bonded in a 6-coordinate geometry to two equivalent Tm3+ and four equivalent Sm+2.50+ atoms.
