The material structure described by Sc2Pt is Cotunnite structured and crystallizes in the orthorhombic Pnma space group. There are two inequivalent Sc sites. In the first Sc site, Sc(1) is bonded in a 3-coordinate geometry to three equivalent Pt(1) atoms. In the second Sc site, Sc(2) is bonded to four equivalent Pt(1) atoms to form a mixture of corner and edge-sharing ScPt4 tetrahedra. Pt(1) is bonded in a 7-coordinate geometry to three equivalent Sc(1) and four equivalent Sc(2) atoms. is represented by the CIF file [CIF]
