AlPt2 is Cotunnite structured and crystallizes in the orthorhombic Pnma space group. There are two inequivalent Pt sites. In the first Pt site, Pt(2) is bonded in a 5-coordinate geometry to five equivalent Al(1) atoms. In the second Pt site, Pt(1) is bonded in a 3-coordinate geometry to five equivalent Al(1) atoms. Al(1) is bonded in a 10-coordinate geometry to five equivalent Pt(1) and five equivalent Pt(2) atoms.
