Materials Data on Y3Ga by Materials Project

Y3Ga is Uranium Silicide structured and crystallizes in the cubic Pm-3m space group. The structure is three-dimensional. Y is bonded to eight equivalent Y and four equivalent Ga atoms to form distorted YY8Ga4 cuboctahedra that share corners with twelve equivalent YY8Ga4 cuboctahedra, edges with eight equivalent GaY12 cuboctahedra, edges with sixteen equivalent YY8Ga4 cuboctahedra, faces with four equivalent GaY12 cuboctahedra, and faces with fourteen equivalent YY8Ga4 cuboctahedra. All Y–Y bond lengths are 3.36 Å. All Y–Ga bond lengths are 3.36 Å. Ga is bonded to twelve equivalent Y atoms to form GaY12 cuboctahedra that share corners with twelve equivalent GaY12 cuboctahedra, edges with twenty-four equivalent YY8Ga4 cuboctahedra, faces with six equivalent GaY12 cuboctahedra, and faces with twelve equivalent YY8Ga4 cuboctahedra.

Materials Data on Y3Ga(FeO3)4 by Materials Project

Y3Fe4GaO12 crystallizes in the tetragonal I-42d space group. The structure is three-dimensional. there are three inequivalent Y3+ sites. In the first Y3+ site, Y3+ is bonded in a body-centered cubic geometry to eight O2- atoms. There are a spread of Y–O bond distances ranging from 2.37–2.45 Å. In the second Y3+ site, Y3+ is bonded in a body-centered cubic geometry to eight O2- atoms. There are a spread of Y–O bond distances ranging from 2.37–2.47 Å. In the third Y3+ site, Y3+ is bonded in a body-centered cubic geometry to eight O2- atoms. There are a spread of Y–O bond distances ranging from 2.37–2.47 Å. There are four inequivalent Fe3+ sites. In the first Fe3+ site, Fe3+ is bonded to six O2- atoms to form FeO6 octahedra that share corners with two equivalent GaO4 tetrahedra and corners with four FeO4 tetrahedra. There are a spread of Fe–O bond distances ranging from 2.04–2.06 Å. In the second Fe3+ site, Fe3+ is bonded to four equivalent O2- atoms to form corner-sharing FeO4 tetrahedra. The corner-sharing octahedral tilt angles are 55°. All Fe–O bond lengths are 1.90 Å. In the third Fe3+ site, Fe3+ is bonded to four O2- atoms to form corner-sharing FeO4 tetrahedra. The corner-sharing octahedral tilt angles are 55°. All Fe–O bond lengths are 1.90 Å. In the fourth Fe3+ site, Fe3+ is bonded to four equivalent O2- atoms to form corner-sharing FeO4 tetrahedra. The corner-sharing octahedral tilt angles are 56°. All Fe–O bond lengths are 1.90 Å. Ga3+ is bonded to four O2- atoms to form GaO4 tetrahedra that share corners with four equivalent FeO6 octahedra. The corner-sharing octahedral tilt angles are 54°. All Ga–O bond lengths are 1.87 Å. There are six inequivalent O2- sites. In the first O2- site, O2- is bonded to two Y3+ and two Fe3+ atoms to form a mixture of distorted edge and corner-sharing OY2Fe2 tetrahedra. In the second O2- site, O2- is bonded to two Y3+ and two Fe3+ atoms to form a mixture of distorted edge and corner-sharing OY2Fe2 tetrahedra. In the third O2- site, O2- is bonded to two Y3+ and two Fe3+ atoms to form a mixture of distorted edge and corner-sharing OY2Fe2 tetrahedra. In the fourth O2- site, O2- is bonded in a 4-coordinate geometry to two Y3+, one Fe3+, and one Ga3+ atom. In the fifth O2- site, O2- is bonded in a 4-coordinate geometry to two Y3+, one Fe3+, and one Ga3+ atom. In the sixth O2- site, O2- is bonded to two Y3+ and two Fe3+ atoms to form a mixture of distorted edge and corner-sharing OY2Fe2 tetrahedra.
