Materials Data on Yb3SnO by Materials Project

Yb3SnO is (Cubic) Perovskite structured and crystallizes in the cubic Pm-3m space group. The structure is three-dimensional. Yb is bonded in a linear geometry to four equivalent Sn and two equivalent O atoms. All Yb–Sn bond lengths are 3.37 Å. Both Yb–O bond lengths are 2.38 Å. Sn is bonded to twelve equivalent Yb atoms to form SnYb12 cuboctahedra that share corners with twelve equivalent SnYb12 cuboctahedra, faces with six equivalent SnYb12 cuboctahedra, and faces with eight equivalent OYb6 octahedra. O is bonded to six equivalent Yb atoms to form OYb6 octahedra that share corners with six equivalent OYb6 octahedra and faces with eight equivalent SnYb12 cuboctahedra. The corner-sharing octahedral tilt angles are 0°.

Materials Data on Yb2Sn2O7 by Materials Project

Yb2Sn2O7 crystallizes in the cubic Fd-3m space group. The structure is three-dimensional. Yb3+ is bonded in a body-centered cubic geometry to eight O2- atoms. There are two shorter (2.28 Å) and six longer (2.54 Å) Yb–O bond lengths. Sn4+ is bonded to six equivalent O2- atoms to form corner-sharing SnO6 octahedra. The corner-sharing octahedral tilt angles are 52°. All Sn–O bond lengths are 2.07 Å. There are two inequivalent O2- sites. In the first O2- site, O2- is bonded to four equivalent Yb3+ atoms to form OYb4 tetrahedra that share corners with sixteen OYb4 tetrahedra and edges with six equivalent OYb2Sn2 tetrahedra. In the second O2- site, O2- is bonded to two equivalent Yb3+ and two equivalent Sn4+ atoms to form a mixture of distorted edge and corner-sharing OYb2Sn2 tetrahedra.
