Materials Data on LiTeHO4 by Materials Project
LiHTeO4 crystallizes in the monoclinic Pm space group. The structure is three-dimensional. Li1+ is bonded to four O2- atoms to form LiO4 tetrahedra that share corners with six TeO6 octahedra and corners with two equivalent LiO4 tetrahedra. The corner-sharing octahedra tilt angles range from 49–60°. There are a spread of Li–O bond distances ranging from 1.95–2.19 Å. There are two inequivalent H1+ sites. In the first H1+ site, H1+ is bonded in a distorted linear geometry to two O2- atoms. There is one shorter (1.01 Å) and one longer (1.64 Å) H–O bond length. In the second H1+ site, H1+ is bonded in a linear geometry to two O2- atoms. There is one shorter (1.02 Å) and one longer (1.59 Å) H–O bond length. There are two inequivalent Te6+ sites. In the first Te6+ site, Te6+ is bonded to six O2- atoms to form TeO6 octahedra that share corners with six equivalent LiO4 tetrahedra and edges with two equivalent TeO6 octahedra. There are a spread of Te–O bond distances ranging from 1.88–2.03 Å. In the second Te6+ site, Te6+ is bonded to six O2- atoms to form TeO6 octahedra that share corners with six equivalent LiO4 tetrahedra and edges with two equivalent TeO6 octahedra. There are a spread of Te–O bond distances ranging from 1.88–2.03 Å. There are six inequivalent O2- sites. In the first O2- site, O2- is bonded in a distorted water-like geometry to one H1+ and one Te6+ atom. In the second O2- site, O2- is bonded in a distorted water-like geometry to one H1+ and one Te6+ atom. In the third O2- site, O2- is bonded in a distorted trigonal planar geometry to one Li1+ and two Te6+ atoms. In the fourth O2- site, O2- is bonded in a distorted trigonal planar geometry to one Li1+ and two Te6+ atoms. In the fifth O2- site, O2- is bonded to two equivalent Li1+, one H1+, and one Te6+ atom to form distorted corner-sharing OLi2TeH trigonal pyramids. In the sixth O2- site, O2- is bonded to two equivalent Li1+, one H1+, and one Te6+ atom to form distorted corner-sharing OLi2TeH trigonal pyramids.
