Materials Data on Yb3Y3Al10O24 by Materials Project
Yb3Y3Al10O24 crystallizes in the cubic I4_132 space group. The structure is three-dimensional. Yb3+ is bonded in a body-centered cubic geometry to eight equivalent O2- atoms. There are four shorter (2.37 Å) and four longer (2.46 Å) Yb–O bond lengths. Y3+ is bonded in a distorted body-centered cubic geometry to eight equivalent O2- atoms. There are four shorter (2.33 Å) and four longer (2.46 Å) Y–O bond lengths. There are two inequivalent Al3+ sites. In the first Al3+ site, Al3+ is bonded to six O2- atoms to form corner-sharing AlO6 octahedra. There is three shorter (1.92 Å) and three longer (1.95 Å) Al–O bond length. In the second Al3+ site, Al3+ is bonded to four O2- atoms to form corner-sharing AlO4 tetrahedra. The corner-sharing octahedra tilt angles range from 48–50°. There is two shorter (1.78 Å) and two longer (1.79 Å) Al–O bond length. There are two inequivalent O2- sites. In the first O2- site, O2- is bonded in a 4-coordinate geometry to two equivalent Y3+ and two Al3+ atoms. In the second O2- site, O2- is bonded in a 4-coordinate geometry to two equivalent Yb3+ and two Al3+ atoms.
