Materials Data on Ca3Al2O12 by Materials Project
Ca3Al2O12 crystallizes in the cubic Ia-3d space group. The structure is three-dimensional. Ca is bonded in a distorted body-centered cubic geometry to eight equivalent O atoms. There are four shorter (2.43 Å) and four longer (2.53 Å) Ca–O bond lengths. Al is bonded in a distorted octahedral geometry to six equivalent O atoms. All Al–O bond lengths are 1.85 Å. O is bonded in a distorted trigonal non-coplanar geometry to two equivalent Ca and one Al atom.
