Materials Data on Li3SiSbCO7 by Materials Project
Li3SiCSbO7 crystallizes in the monoclinic P2_1/m space group. The structure is three-dimensional. there are two inequivalent Li1+ sites. In the first Li1+ site, Li1+ is bonded in a 5-coordinate geometry to five O2- atoms. There are a spread of Li–O bond distances ranging from 1.95–2.45 Å. In the second Li1+ site, Li1+ is bonded in a distorted see-saw-like geometry to four O2- atoms. There are a spread of Li–O bond distances ranging from 1.98–2.46 Å. Si4+ is bonded in a tetrahedral geometry to four O2- atoms. There are a spread of Si–O bond distances ranging from 1.64–1.68 Å. C4+ is bonded in a trigonal planar geometry to three O2- atoms. There are a spread of C–O bond distances ranging from 1.28–1.33 Å. Sb3+ is bonded in a 5-coordinate geometry to five O2- atoms. There are a spread of Sb–O bond distances ranging from 2.07–2.43 Å. There are six inequivalent O2- sites. In the first O2- site, O2- is bonded in a rectangular see-saw-like geometry to three Li1+ and one C4+ atom. In the second O2- site, O2- is bonded in a 1-coordinate geometry to one Li1+, one C4+, and one Sb3+ atom. In the third O2- site, O2- is bonded in a bent 120 degrees geometry to one Li1+ and one C4+ atom. In the fourth O2- site, O2- is bonded in a 4-coordinate geometry to two Li1+, one Si4+, and one Sb3+ atom. In the fifth O2- site, O2- is bonded in a distorted tetrahedral geometry to two equivalent Li1+, one Si4+, and one Sb3+ atom. In the sixth O2- site, O2- is bonded in a 4-coordinate geometry to two equivalent Li1+, one Si4+, and one Sb3+ atom.
