The material structure described by ThPtAl crystallizes in the hexagonal P-62m space group. Th(1) is bonded in a 5-coordinate geometry to one Pt(2) and four equivalent Pt(1) atoms. There are two inequivalent Pt sites. In the first Pt site, Pt(2) is bonded in a 9-coordinate geometry to three equivalent Th(1) and six equivalent Al(1) atoms. In the second Pt site, Pt(1) is bonded in a 9-coordinate geometry to six equivalent Th(1) and three equivalent Al(1) atoms. Al(1) is bonded in a 4-coordinate geometry to two equivalent Pt(1) and two equivalent Pt(2) atoms. is represented by the CIF file [CIF]
