Materials Data on Tl2Pt3 by Materials Project

Pt3Tl2 crystallizes in the hexagonal P6_3/mmc space group. The structure is three-dimensional. Pt+0.67- is bonded in a 5-coordinate geometry to six equivalent Pt+0.67- and five Tl1+ atoms. There are a spread of Pt–Pt bond distances ranging from 2.85–2.98 Å. There are a spread of Pt–Tl bond distances ranging from 2.84–3.02 Å. There are three inequivalent Tl1+ sites. In the first Tl1+ site, Tl1+ is bonded in a 6-coordinate geometry to six equivalent Pt+0.67- atoms. In the second Tl1+ site, Tl1+ is bonded in a 6-coordinate geometry to six equivalent Pt+0.67- atoms. In the third Tl1+ site, Tl1+ is bonded in a distorted q6 geometry to nine equivalent Pt+0.67- atoms.

Materials Data on Tl2Pt by Materials Project

PtTl2 crystallizes in the orthorhombic Fmmm space group. The structure is three-dimensional. Pt2- is bonded to two equivalent Pt2- and four equivalent Tl1+ atoms to form distorted corner-sharing PtTl4Pt2 octahedra. The corner-sharing octahedra tilt angles range from 0–41°. Both Pt–Pt bond lengths are 2.82 Å. All Pt–Tl bond lengths are 2.78 Å. Tl1+ is bonded in a distorted bent 150 degrees geometry to two equivalent Pt2- atoms.
