Materials Data on La2S2O by Materials Project

Abstract

La2S2O crystallizes in the monoclinic P2_1/c space group. The structure is three-dimensional. there are two inequivalent La3+ sites. In the first La3+ site, La3+ is bonded in a 1-coordinate geometry to six S2- and one O2- atom. There are a spread of La–S bond distances ranging from 2.92–3.06 Å. The La–O bond length is 2.39 Å. In the second La3+ site, La3+ is bonded in a 7-coordinate geometry to four S2- and three equivalent O2- atoms. There are a spread of La–S bond distances ranging from 2.95–3.25 Å. There are a spread of La–O bond distances ranging from 2.41–2.44 Å. There are two inequivalent S2- sites. In the first S2- site, S2- is bonded in a 5-coordinate geometry to five La3+ atoms. In the second S2- site, S2- is bonded in a 5-coordinate geometry to five La3+ atoms. O2- is bonded to four La3+ atoms to form a mixture of corner and edge-sharing OLa4 tetrahedra.
