Materials Data on Y2Te5O13 by Materials Project
Y2Te5O13 crystallizes in the triclinic P-1 space group. The structure is two-dimensional and consists of one Y2Te5O13 sheet oriented in the (0, 0, 1) direction. there are two inequivalent Y3+ sites. In the first Y3+ site, Y3+ is bonded in a distorted pentagonal bipyramidal geometry to seven O2- atoms. There are a spread of Y–O bond distances ranging from 2.23–2.80 Å. In the second Y3+ site, Y3+ is bonded in a 8-coordinate geometry to eight O2- atoms. There are a spread of Y–O bond distances ranging from 2.32–2.63 Å. There are five inequivalent Te4+ sites. In the first Te4+ site, Te4+ is bonded in a 3-coordinate geometry to three O2- atoms. There is two shorter (1.90 Å) and one longer (1.94 Å) Te–O bond length. In the second Te4+ site, Te4+ is bonded in a 4-coordinate geometry to four O2- atoms. There are a spread of Te–O bond distances ranging from 1.91–2.47 Å. In the third Te4+ site, Te4+ is bonded in a 4-coordinate geometry to four O2- atoms. There are a spread of Te–O bond distances ranging from 1.88–2.55 Å. In the fourth 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 1.89–2.16 Å. In the fifth Te4+ site, Te4+ is bonded in a 5-coordinate geometry to four O2- atoms. There are a spread of Te–O bond distances ranging from 1.90–2.75 Å. There are thirteen inequivalent O2- sites. In the first O2- site, O2- is bonded in a linear geometry to one Y3+ and one Te4+ atom. In the second O2- site, O2- is bonded in a 2-coordinate geometry to one Y3+ and two Te4+ atoms. In the third O2- site, O2- is bonded in a bent 120 degrees geometry to two Te4+ atoms.
