Materials Data on Ca(Cu3O4)2 by Materials Project
Ca(Cu3O4)2 crystallizes in the cubic Fm-3m space group. The structure is three-dimensional. Ca2+ is bonded in a body-centered cubic geometry to eight equivalent O2- atoms. All Ca–O bond lengths are 2.33 Å. Cu+2.33+ is bonded in a square co-planar geometry to four equivalent O2- atoms. All Cu–O bond lengths are 1.92 Å. O2- is bonded to one Ca2+ and three equivalent Cu+2.33+ atoms to form a mixture of distorted edge and corner-sharing OCaCu3 trigonal pyramids.
