Materials Data on In7Te10 by Materials Project
In7Te10 crystallizes in the trigonal R32 space group. The structure is three-dimensional. there are three inequivalent In+2.86+ sites. In the first In+2.86+ site, In+2.86+ is bonded to four Te2- atoms to form a mixture of edge and corner-sharing InTe4 tetrahedra. There are a spread of In–Te bond distances ranging from 2.78–2.91 Å. In the second In+2.86+ site, In+2.86+ is bonded to four Te2- atoms to form corner-sharing InTe4 tetrahedra. There are a spread of In–Te bond distances ranging from 2.78–2.88 Å. In the third In+2.86+ site, In+2.86+ is bonded in a trigonal non-coplanar geometry to three equivalent Te2- atoms. All In–Te bond lengths are 2.89 Å. There are five inequivalent Te2- sites. In the first Te2- site, Te2- is bonded in a 3-coordinate geometry to three In+2.86+ atoms. In the second Te2- site, Te2- is bonded in an L-shaped geometry to two equivalent In+2.86+ atoms. In the third Te2- site, Te2- is bonded in a distorted trigonal non-coplanar geometry to three In+2.86+ atoms. In the fourth Te2- site, Te2- is bonded in a water-like geometry to two equivalent In+2.86+ atoms. In the fifth Te2- site, Te2- is bonded in a distorted trigonal non-coplanar geometry to three equivalent In+2.86+ atoms.
