Materials Data on TmSbMo2O9 by Materials Project

Abstract

TmMo2SbO9 crystallizes in the monoclinic C2/c space group. The structure is three-dimensional. there are two inequivalent Tm3+ sites. In the first Tm3+ site, Tm3+ is bonded in a 8-coordinate geometry to eight O2- atoms. There are a spread of Tm–O bond distances ranging from 2.28–2.43 Å. In the second Tm3+ site, Tm3+ is bonded in a 8-coordinate geometry to eight O2- atoms. There are a spread of Tm–O bond distances ranging from 2.31–2.39 Å. There are two inequivalent Mo6+ sites. In the first Mo6+ site, Mo6+ is bonded in a tetrahedral geometry to four O2- atoms. There are a spread of Mo–O bond distances ranging from 1.77–1.86 Å. In the second Mo6+ site, Mo6+ is bonded in a tetrahedral geometry to four O2- atoms. There are a spread of Mo–O bond distances ranging from 1.77–1.84 Å. Sb3+ is bonded in a distorted rectangular see-saw-like geometry to four O2- atoms. There are a spread of Sb–O bond distances ranging from 2.02–2.30 Å. There are nine inequivalent O2- sites. In the first O2- site, O2- is bonded in a distorted linear geometry to one Tm3+ and one Mo6+ atom. In the second O2- site, O2- is bonded in a distorted trigonal planar geometry to one Tm3+ and two equivalent Sb3+ atoms. In the third O2- site, O2- is bonded in a distorted bent 150 degrees geometry to one Tm3+ and one Mo6+ atom. In the fourth O2- site, O2- is bonded in a distorted bent 150 degrees geometry to one Tm3+ and one Mo6+ atom. In the fifth O2- site, O2- is bonded in a 3-coordinate geometry to one Tm3+, one Mo6+, and one Sb3+ atom. In the sixth O2- site, O2- is bonded in a linear geometry to one Tm3+ and one Mo6+ atom. In the seventh O2- site, O2- is bonded in a distorted bent 150 degrees geometry to one Tm3+ and one Mo6+ atom. In the eighth O2- site, O2- is bonded in a distorted bent 150 degrees geometry to one Tm3+ and one Mo6+ atom. In the ninth O2- site, O2- is bonded in a bent 150 degrees geometry to one Mo6+ and one Sb3+ atom.
