Materials Data on In4Te3 by Materials Project
In4Te3 crystallizes in the orthorhombic Pnnm space group. The structure is three-dimensional. there are four inequivalent In+1.50+ sites. In the first In+1.50+ site, In+1.50+ is bonded in a trigonal non-coplanar geometry to three Te2- atoms. There are one shorter (2.87 Å) and two longer (2.96 Å) In–Te bond lengths. In the second In+1.50+ site, In+1.50+ is bonded in a distorted square co-planar geometry to four Te2- atoms. There are two shorter (3.05 Å) and two longer (3.61 Å) In–Te bond lengths. In the third In+1.50+ site, In+1.50+ is bonded to five Te2- atoms to form edge-sharing InTe5 square pyramids. There are a spread of In–Te bond distances ranging from 3.23–3.55 Å. In the fourth In+1.50+ site, In+1.50+ is bonded in a trigonal non-coplanar geometry to three Te2- atoms. There are two shorter (2.89 Å) and one longer (2.95 Å) In–Te bond lengths. There are three inequivalent Te2- sites. In the first Te2- site, Te2- is bonded in a 5-coordinate geometry to five In+1.50+ atoms. In the second Te2- site, Te2- is bonded in a 5-coordinate geometry to five In+1.50+ atoms. In the third Te2- site, Te2- is bonded to five In+1.50+ atoms to form distorted edge-sharing TeIn5 square pyramids.
