The compound described by CePtAl crystallizes in the orthorhombic Pnma space group. Ce(1) is bonded in a 11-coordinate geometry to five equivalent Pt(1) and six equivalent Al(1) atoms. Pt(1) is bonded in a 9-coordinate geometry to five equivalent Ce(1) and four equivalent Al(1) atoms. Al(1) is bonded to six equivalent Ce(1) and four equivalent Pt(1) atoms to form a mixture of distorted face, corner, and edge-sharing AlCe6Pt4 tetrahedra. is represented by the CIF card [CIF]
