The structure described by SrCaAl4 is Cubic Laves-derived structured and crystallizes in the cubic F-43m space group. Sr(1) is bonded in a 16-coordinate geometry to four equivalent Ca(1) and twelve equivalent Al(1) atoms. Ca(1) is bonded in a 16-coordinate geometry to four equivalent Sr(1) and twelve equivalent Al(1) atoms. Al(1) is bonded to three equivalent Sr(1), three equivalent Ca(1), and six equivalent Al(1) atoms to form a mixture of face, corner, and edge-sharing AlSr3Ca3Al6 cuboctahedra. is represented by the CIF file [CIF]
