Materials Data on EuTlPS4 by Materials Project
TlEuPS4 crystallizes in the monoclinic P2_1/c space group. The structure is three-dimensional. Eu2+ is bonded in a 8-coordinate geometry to eight S2- atoms. There are a spread of Eu–S bond distances ranging from 2.97–3.47 Å. Tl1+ is bonded in a 8-coordinate geometry to eight S2- atoms. There are a spread of Tl–S bond distances ranging from 3.27–3.50 Å. P5+ is bonded in a tetrahedral geometry to four S2- atoms. There are a spread of P–S bond distances ranging from 2.05–2.07 Å. There are four inequivalent S2- sites. In the first S2- site, S2- is bonded in a 1-coordinate geometry to two equivalent Eu2+, two equivalent Tl1+, and one P5+ atom. In the second S2- site, S2- is bonded in a 5-coordinate geometry to three equivalent Eu2+, one Tl1+, and one P5+ atom. In the third S2- site, S2- is bonded in a 5-coordinate geometry to one Eu2+, three equivalent Tl1+, and one P5+ atom. In the fourth S2- site, S2- is bonded in a 1-coordinate geometry to two equivalent Eu2+, two equivalent Tl1+, and one P5+ atom.
