Materials Data on NaIn(TeO3)2 by Materials Project
NaIn(TeO3)2 crystallizes in the orthorhombic Pbca space group. The structure is three-dimensional. Na1+ is bonded in a 8-coordinate geometry to eight O2- atoms. There are a spread of Na–O bond distances ranging from 2.46–3.11 Å. In3+ is bonded to six O2- atoms to form edge-sharing InO6 octahedra. There are a spread of In–O bond distances ranging from 2.15–2.23 Å. There are two inequivalent Te4+ sites. In the first Te4+ site, Te4+ is bonded in a 3-coordinate geometry to three O2- atoms. There are a spread of Te–O bond distances ranging from 1.88–1.93 Å. In the second Te4+ site, Te4+ is bonded in a 5-coordinate geometry to five O2- atoms. There are a spread of Te–O bond distances ranging from 1.91–2.72 Å. There are six inequivalent O2- sites. In the first O2- site, O2- is bonded in a 3-coordinate geometry to one Na1+, one In3+, and one Te4+ atom. In the second O2- site, O2- is bonded in a 4-coordinate geometry to one Na1+, two equivalent In3+, and one Te4+ atom. In the third O2- site, O2- is bonded in a distorted trigonal non-coplanar geometry to one Na1+, one In3+, and one Te4+ atom. In the fourth O2- site, O2- is bonded in a 4-coordinate geometry to one Na1+, one In3+, and two equivalent Te4+ atoms. In the fifth O2- site, O2- is bonded in a 4-coordinate geometry to two equivalent Na1+ and two Te4+ atoms. In the sixth O2- site, O2- is bonded in a 2-coordinate geometry to two equivalent Na1+, one In3+, and one Te4+ atom.
