Materials Data on Ca3Si3(SnO6)2 by Materials Project

Ca3Si3(SnO6)2 crystallizes in the cubic Ia-3d space group. The structure is three-dimensional. Ca2+ is bonded in a distorted body-centered cubic geometry to eight equivalent O2- atoms. There are four shorter (2.46 Å) and four longer (2.56 Å) Ca–O bond lengths. Sn3+ is bonded to six equivalent O2- atoms to form SnO6 octahedra that share corners with six equivalent SiO4 tetrahedra. All Sn–O bond lengths are 2.26 Å. Si4+ is bonded to four equivalent O2- atoms to form SiO4 tetrahedra that share corners with four equivalent SnO6 octahedra. The corner-sharing octahedral tilt angles are 53°. All Si–O bond lengths are 1.67 Å. O2- is bonded in a 4-coordinate geometry to two equivalent Ca2+, one Sn3+, and one Si4+ atom.
