Materials Data on TmSb(PbO3)2 by Materials Project

Abstract

TmSb(PbO3)2 crystallizes in the trigonal R-3 space group. The structure is three-dimensional. Tm3+ is bonded to six equivalent O2- atoms to form TmO6 octahedra that share corners with six equivalent SbO6 octahedra. The corner-sharing octahedral tilt angles are 21°. All Tm–O bond lengths are 2.22 Å. Pb2+ is bonded in a 3-coordinate geometry to nine equivalent O2- atoms. There are a spread of Pb–O bond distances ranging from 2.58–2.98 Å. Sb5+ is bonded to six equivalent O2- atoms to form SbO6 octahedra that share corners with six equivalent TmO6 octahedra. The corner-sharing octahedral tilt angles are 21°. All Sb–O bond lengths are 2.01 Å. O2- is bonded in a 2-coordinate geometry to one Tm3+, three equivalent Pb2+, and one Sb5+ atom.
