Materials Data on TmAsSe by Materials Project
TmAsSe is Matlockite structured and crystallizes in the monoclinic P2_1/c space group. The structure is three-dimensional. Tm3+ is bonded in a 9-coordinate geometry to four equivalent As1- and five equivalent Se2- atoms. There are a spread of Tm–As bond distances ranging from 3.05–3.13 Å. There are a spread of Tm–Se bond distances ranging from 2.87–3.01 Å. As1- is bonded in a 8-coordinate geometry to four equivalent Tm3+ and four equivalent As1- atoms. There are a spread of As–As bond distances ranging from 2.57–2.92 Å. Se2- is bonded in a 5-coordinate geometry to five equivalent Tm3+ atoms.
