Materials Data on InTeI7 by Materials Project
InTeI7 crystallizes in the orthorhombic Pna2_1 space group. The structure is two-dimensional and consists of two InTeI7 sheets oriented in the (0, 0, 1) direction. there are two inequivalent In3+ sites. In the first In3+ site, In3+ is bonded to four I1- atoms to form InI4 tetrahedra that share corners with two TeI6 octahedra and an edgeedge with one TeI6 octahedra. The corner-sharing octahedra tilt angles range from 62–65°. There are a spread of In–I bond distances ranging from 2.76–2.80 Å. In the second In3+ site, In3+ is bonded to four I1- atoms to form InI4 tetrahedra that share corners with two equivalent TeI6 octahedra. The corner-sharing octahedra tilt angles range from 51–63°. There are a spread of In–I bond distances ranging from 2.76–2.81 Å. There are two inequivalent Te4+ sites. In the first Te4+ site, Te4+ is bonded to six I1- atoms to form distorted TeI6 octahedra that share corners with three InI4 tetrahedra. There are a spread of Te–I bond distances ranging from 2.75–3.66 Å. In the second Te4+ site, Te4+ is bonded to six I1- atoms to form distorted TeI6 octahedra that share a cornercorner with one InI4 tetrahedra and an edgeedge with one InI4 tetrahedra. There are a spread of Te–I bond distances ranging from 2.77–3.60 Å. There are fourteen inequivalent I1- sites. In the first I1- site, I1- is bonded in a single-bond geometry to one Te4+ atom. In the second I1- site, I1- is bonded in a distorted single-bond geometry to one In3+ and one Te4+ atom. In the third I1- site, I1- is bonded in a distorted single-bond geometry to one In3+ and one Te4+ atom. In the fourth I1- site, I1- is bonded in a distorted single-bond geometry to one In3+ and one Te4+ atom. In the fifth I1- site, I1- is bonded in a single-bond geometry to one Te4+ atom. In the sixth I1- site, I1- is bonded in a single-bond geometry to one Te4+ atom. In the seventh I1- site, I1- is bonded in a single-bond geometry to one In3+ atom. In the eighth I1- site, I1- is bonded in a single-bond geometry to one Te4+ atom. In the ninth I1- site, I1- is bonded in a distorted L-shaped geometry to one In3+ and one Te4+ atom. In the tenth I1- site, I1- is bonded in a single-bond geometry to one In3+ atom. In the eleventh I1- site, I1- is bonded in a distorted bent 120 degrees geometry to one In3+ and one Te4+ atom. In the twelfth I1- site, I1- is bonded in a distorted bent 120 degrees geometry to one In3+ and one Te4+ atom. In the thirteenth I1- site, I1- is bonded in a single-bond geometry to one Te4+ atom. In the fourteenth I1- site, I1- is bonded in a single-bond geometry to one Te4+ atom.
