Materials Data on La(SbO3)3 by Materials Project
La(SbO3)3 crystallizes in the orthorhombic Cmcm space group. The structure is three-dimensional. La3+ is bonded in a 7-coordinate geometry to seven O2- atoms. There are a spread of La–O bond distances ranging from 2.44–2.72 Å. There are two inequivalent Sb5+ sites. In the first Sb5+ site, Sb5+ is bonded to six O2- atoms to form a mixture of corner and edge-sharing SbO6 octahedra. The corner-sharing octahedra tilt angles range from 34–52°. There are a spread of Sb–O bond distances ranging from 1.95–2.04 Å. In the second Sb5+ site, Sb5+ is bonded to six O2- atoms to form corner-sharing SbO6 octahedra. The corner-sharing octahedra tilt angles range from 51–52°. There are two shorter (2.02 Å) and four longer (2.03 Å) Sb–O bond lengths. There are four inequivalent O2- sites. In the first O2- site, O2- is bonded in a distorted bent 150 degrees geometry to one La3+ and two equivalent Sb5+ atoms. In the second O2- site, O2- is bonded in a 3-coordinate geometry to one La3+ and two equivalent Sb5+ atoms. In the third O2- site, O2- is bonded in a bent 120 degrees geometry to two Sb5+ atoms. In the fourth O2- site, O2- is bonded in a distorted trigonal planar geometry to one La3+ and two Sb5+ atoms.
