Materials Data on Yb3SiO by Materials Project
Yb3SiO is Orthorhombic Perovskite structured and crystallizes in the orthorhombic Pnma space group. The structure is three-dimensional. there are two inequivalent Yb2+ sites. In the first Yb2+ site, Yb2+ is bonded in a distorted linear geometry to four equivalent Si4- and two equivalent O2- atoms. There are a spread of Yb–Si bond distances ranging from 3.10–3.52 Å. Both Yb–O bond lengths are 2.34 Å. In the second Yb2+ site, Yb2+ is bonded in a distorted linear geometry to four equivalent Si4- and two equivalent O2- atoms. There are a spread of Yb–Si bond distances ranging from 3.09–3.50 Å. Both Yb–O bond lengths are 2.34 Å. Si4- is bonded to twelve Yb2+ atoms to form distorted SiYb12 cuboctahedra that share corners with twelve equivalent SiYb12 cuboctahedra, faces with six equivalent SiYb12 cuboctahedra, and faces with eight equivalent OYb6 octahedra. O2- is bonded to six Yb2+ atoms to form OYb6 octahedra that share corners with six equivalent OYb6 octahedra and faces with eight equivalent SiYb12 cuboctahedra. The corner-sharing octahedral tilt angles are 10°.
