Materials Data on TlInS2 by Materials Project

Abstract

TlInS2 crystallizes in the triclinic P1 space group. The structure is three-dimensional. Tl1+ is bonded in a 6-coordinate geometry to six S2- atoms. There are a spread of Tl–S bond distances ranging from 3.03–3.91 Å. In3+ is bonded in a distorted T-shaped geometry to three S2- atoms. There are a spread of In–S bond distances ranging from 2.78–2.90 Å. There are two inequivalent S2- sites. In the first S2- site, S2- is bonded in a 4-coordinate geometry to three equivalent Tl1+, two equivalent In3+, and two equivalent S2- atoms. There are one shorter (2.10 Å) and one longer (3.15 Å) S–S bond lengths. In the second S2- site, S2- is bonded in a 4-coordinate geometry to three equivalent Tl1+, one In3+, and two equivalent S2- atoms.
