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.
Ca2Pt2Al crystallizes in the monoclinic C2/c space group. Ca(1) is bonded in a 6-coordinate geometry to six equivalent Pt(1) atoms. There are a spread of Ca(1)-Pt(1) bond distances ranging from 3.06-3.09 Å. Pt(1) is bonded in a 8-coordinate geometry to six equivalent Ca(1) and two equivalent Al(1) atoms. There is one shorter (2.50 Å) and one longer (2.53 Å) Pt(1)-Al(1) bond length. Al(1) is bonded in a 4-coordinate geometry to four equivalent Pt(1) atoms.
