Materials Data on Sr3Lu2O12 by Materials Project
Sr3Lu2O12 crystallizes in the cubic Ia-3d space group. The structure is three-dimensional. Sr is bonded to eight equivalent O atoms to form distorted edge-sharing SrO8 hexagonal bipyramids. There are four shorter (2.66 Å) and four longer (2.69 Å) Sr–O bond lengths. Lu is bonded in a distorted hexagonal planar geometry to six equivalent O atoms. All Lu–O bond lengths are 2.17 Å. O is bonded in a trigonal non-coplanar geometry to two equivalent Sr and one Lu atom.
