The material described by Ca2Pt2Al crystallizes in the monoclinic C2/c space group. Ca(1) is bonded in a 6-coordinate geometry to six equivalent Pt(1) atoms. Pt(1) is bonded in a 8-coordinate geometry to six equivalent Ca(1) and two equivalent Al(1) atoms. Al(1) is bonded in a 4-coordinate geometry to four equivalent Pt(1) atoms. is represented by the CIF file [CIF]
