Materials Data on Eu3Ga5O12 by Materials Project
Eu3Ga5O12 crystallizes in the cubic Ia-3d space group. The structure is three-dimensional. Eu3+ is bonded in a body-centered cubic geometry to eight equivalent O2- atoms. There are four shorter (2.42 Å) and four longer (2.54 Å) Eu–O bond lengths. There are two inequivalent Ga3+ sites. In the first Ga3+ site, Ga3+ is bonded to four equivalent O2- atoms to form corner-sharing GaO4 tetrahedra. The corner-sharing octahedral tilt angles are 51°. All Ga–O bond lengths are 1.88 Å. In the second Ga3+ site, Ga3+ is bonded to six equivalent O2- atoms to form corner-sharing GaO6 octahedra. All Ga–O bond lengths are 2.03 Å. O2- is bonded in a 4-coordinate geometry to two equivalent Eu3+ and two Ga3+ atoms.
