Materials Data on Y3Sc2(GaO4)3 by Materials Project

Y3Sc2Ga3O12 crystallizes in the cubic Ia-3d space group. The structure is three-dimensional. Y3+ is bonded in a body-centered cubic geometry to eight equivalent O2- atoms. There are four shorter (2.39 Å) and four longer (2.47 Å) Y–O bond lengths. Sc3+ is bonded to six equivalent O2- atoms to form ScO6 octahedra that share corners with six equivalent GaO4 tetrahedra. All Sc–O bond lengths are 2.11 Å. Ga3+ is bonded to four equivalent O2- atoms to form GaO4 tetrahedra that share corners with four equivalent ScO6 octahedra. The corner-sharing octahedral tilt angles are 55°. All Ga–O bond lengths are 1.87 Å. O2- is bonded in a 4-coordinate geometry to two equivalent Y3+, one Sc3+, and one Ga3+ atom.
