The material described by Al3Pt5 crystallizes in the orthorhombic Pbam space group. There are three inequivalent Pt sites. In the first Pt site, Pt(1) is bonded in a 6-coordinate geometry to two equivalent Al(2) and four equivalent Al(1) atoms. In the second Pt site, Pt(2) is bonded in a 5-coordinate geometry to one Al(2) and four equivalent Al(1) atoms. In the third Pt site, Pt(3) is bonded in a 6-coordinate geometry to two equivalent Al(2) and four equivalent Al(1) atoms. There are two inequivalent Al sites. In the first Al site, Al(1) is bonded in a 10-coordinate geometry to two equivalent Pt(3), four equivalent Pt(1), and four equivalent Pt(2) atoms. In the second Al site, Al(2) is bonded in a body-centered cubic geometry to two equivalent Pt(2), two equivalent Pt(3), and four equivalent Pt(1) atoms. is represented by the CIF card [CIF]
