Materials Data on Li2Te2O5 by Materials Project
Li2Te2O5 crystallizes in the monoclinic P2_1/c space group. The structure is two-dimensional and consists of one Li2Te2O5 sheet oriented in the (1, 0, 0) direction. there are two inequivalent Li1+ sites. In the first Li1+ site, Li1+ is bonded to four O2- atoms to form a mixture of distorted corner and edge-sharing LiO4 tetrahedra. There are a spread of Li–O bond distances ranging from 2.00–2.06 Å. In the second Li1+ site, Li1+ is bonded to four O2- atoms to form a mixture of distorted corner and edge-sharing LiO4 trigonal pyramids. There are a spread of Li–O bond distances ranging from 2.01–2.07 Å. There are two inequivalent Te4+ sites. In the first Te4+ site, Te4+ is bonded in a distorted rectangular see-saw-like geometry to four O2- atoms. There are a spread of Te–O bond distances ranging from 1.89–2.37 Å. In the second Te4+ site, Te4+ is bonded in a rectangular see-saw-like geometry to four O2- atoms. There are a spread of Te–O bond distances ranging from 1.88–2.28 Å. There are five inequivalent O2- sites. In the first O2- site, O2- is bonded in a 4-coordinate geometry to three Li1+ and one Te4+ atom. In the second O2- site, O2- is bonded in a distorted bent 150 degrees geometry to two Te4+ atoms. In the third O2- site, O2- is bonded in a distorted trigonal planar geometry to one Li1+ and two Te4+ atoms. In the fourth O2- site, O2- is bonded to three Li1+ and one Te4+ atom to form distorted corner-sharing OLi3Te trigonal pyramids. In the fifth O2- site, O2- is bonded in a distorted trigonal planar geometry to one Li1+ and two Te4+ atoms.
