Materials Data on TmSc(BO3)2 by Materials Project
TmSc(BO3)2 is Calcite-derived structured and 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 ScO6 octahedra. The corner-sharing octahedral tilt angles are 57°. All Tm–O bond lengths are 2.27 Å. Sc3+ is bonded to six equivalent O2- atoms to form ScO6 octahedra that share corners with six equivalent TmO6 octahedra. The corner-sharing octahedral tilt angles are 57°. All Sc–O bond lengths are 2.14 Å. B3+ is bonded in a trigonal planar geometry to three equivalent O2- atoms. All B–O bond lengths are 1.39 Å. O2- is bonded in a distorted trigonal planar geometry to one Tm3+, one Sc3+, and one B3+ atom.
