Materials Data on YbAl3(BO3)4 by Materials Project
YbAl3(BO3)4 is Calcite-derived structured and crystallizes in the trigonal R32 space group. The structure is three-dimensional. Yb3+ is bonded to six equivalent O2- atoms to form distorted YbO6 pentagonal pyramids that share corners with six equivalent AlO6 octahedra. The corner-sharing octahedral tilt angles are 60°. All Yb–O bond lengths are 2.38 Å. Al3+ is bonded to six O2- atoms to form AlO6 octahedra that share corners with two equivalent YbO6 pentagonal pyramids and edges with two equivalent AlO6 octahedra. There are a spread of Al–O bond distances ranging from 1.86–1.95 Å. There are two inequivalent B3+ sites. In the first B3+ site, B3+ is bonded in a trigonal planar geometry to three O2- atoms. There is two shorter (1.37 Å) and one longer (1.39 Å) B–O bond length. In the second B3+ site, B3+ is bonded in a trigonal planar geometry to three equivalent O2- atoms. All B–O bond lengths are 1.38 Å. There are three inequivalent O2- sites. In the first O2- site, O2- is bonded in a distorted trigonal planar geometry to two equivalent Al3+ and one B3+ atom. In the second O2- site, O2- is bonded in a distorted trigonal planar geometry to two equivalent Al3+ and one B3+ atom. In the third O2- site, O2- is bonded in a 3-coordinate geometry to one Yb3+, one Al3+, and one B3+ atom.
