The material described by CePtAl2 crystallizes in the orthorhombic Cmcm space group. Ce(1) is bonded in a 13-coordinate geometry to three equivalent Pt(1) and ten equivalent Al(1) atoms. Pt(1) is bonded in a 9-coordinate geometry to three equivalent Ce(1) and six equivalent Al(1) atoms. Al(1) is bonded in a 3-coordinate geometry to five equivalent Ce(1) and three equivalent Pt(1) atoms. is represented by the CIF file [CIF]
