Materials Data on La3SbO3 by Materials Project

La3SbO3 crystallizes in the monoclinic C2/m space group. The structure is three-dimensional. there are three inequivalent La3+ sites. In the first La3+ site, La3+ is bonded in a 4-coordinate geometry to four equivalent Sb3- and four O2- atoms. There are two shorter (3.58 Å) and two longer (3.60 Å) La–Sb bond lengths. There are a spread of La–O bond distances ranging from 2.39–2.73 Å. In the second La3+ site, La3+ is bonded in a distorted see-saw-like geometry to two equivalent Sb3- and four O2- atoms. Both La–Sb bond lengths are 3.36 Å. There are a spread of La–O bond distances ranging from 2.34–2.59 Å. In the third La3+ site, La3+ is bonded in a distorted see-saw-like geometry to two equivalent Sb3- and four O2- atoms. Both La–Sb bond lengths are 3.42 Å. There are a spread of La–O bond distances ranging from 2.33–2.45 Å. Sb3- is bonded in a body-centered cubic geometry to eight La3+ atoms. There are three inequivalent O2- sites. In the first O2- site, O2- is bonded to four La3+ atoms to form a mixture of corner and edge-sharing OLa4 tetrahedra. In the second O2- site, O2- is bonded to four La3+ atoms to form a mixture of distorted corner and edge-sharing OLa4 trigonal pyramids. In the third O2- site, O2- is bonded to four La3+ atoms to form a mixture of corner and edge-sharing OLa4 trigonal pyramids.
