Materials Data on La3Si2ClO8 by Materials Project

Abstract

La3Si2O8Cl crystallizes in the monoclinic C2/c space group. The structure is three-dimensional. there are two inequivalent La3+ sites. In the first La3+ site, La3+ is bonded in a 9-coordinate geometry to eight O2- and one Cl1- atom. There are a spread of La–O bond distances ranging from 2.61–2.70 Å. The La–Cl bond length is 2.99 Å. In the second La3+ site, La3+ is bonded in a 9-coordinate geometry to eight O2- and one Cl1- atom. There are a spread of La–O bond distances ranging from 2.48–2.92 Å. The La–Cl bond length is 2.93 Å. Si4+ is bonded in a tetrahedral geometry to four O2- atoms. There are a spread of Si–O bond distances ranging from 1.63–1.66 Å. There are four inequivalent O2- sites. In the first O2- site, O2- is bonded in a 1-coordinate geometry to three La3+ and one Si4+ atom. In the second O2- site, O2- is bonded in a distorted single-bond geometry to three La3+ and one Si4+ atom. In the third O2- site, O2- is bonded in a 1-coordinate geometry to three equivalent La3+ and one Si4+ atom. In the fourth O2- site, O2- is bonded in a 1-coordinate geometry to three La3+ and one Si4+ atom. Cl1- is bonded in a 3-coordinate geometry to three La3+ atoms.
