Title: Materials Data on La2Se2O by Materials Project

Abstract

La2Se2O 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 Se2- and one O2- atom. There are a spread of La–Se bond distances ranging from 3.00–3.16 Å. The La–O bond length is 2.42 Å. In the second La3+ site, La3+ is bonded in a 7-coordinate geometry to three Se2- and three equivalent O2- atoms. There are a spread of La–Se bond distances ranging from 3.06–3.19 Å. There are one shorter (2.44 Å) and two longer (2.47 Å) La–O bond lengths. There are two inequivalent Se2- sites. In the first Se2- site, Se2- is bonded in a 5-coordinate geometry to five La3+ atoms. In the second Se2- site, Se2- is bonded in a 4-coordinate geometry to four La3+ atoms. O2- is bonded to four La3+ atoms to form a mixture of edge and corner-sharing OLa4 tetrahedra.
