Materials Data on CaSn(BO3)2 by Materials Project
CaSn(BO3)2 is Calcite-derived structured and crystallizes in the trigonal R-3 space group. The structure is three-dimensional. Ca2+ is bonded to six equivalent O2- atoms to form CaO6 octahedra that share corners with six equivalent SnO6 octahedra. The corner-sharing octahedral tilt angles are 58°. All Ca–O bond lengths are 2.40 Å. B3+ is bonded in a trigonal planar geometry to three equivalent O2- atoms. All B–O bond lengths are 1.39 Å. Sn4+ is bonded to six equivalent O2- atoms to form SnO6 octahedra that share corners with six equivalent CaO6 octahedra. The corner-sharing octahedral tilt angles are 58°. All Sn–O bond lengths are 2.09 Å. O2- is bonded in a distorted trigonal planar geometry to one Ca2+, one B3+, and one Sn4+ atom.
