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.
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. There is one shorter (2.70 Å) and two longer (2.87 Å) Sc(1)-Pt(1) bond lengths. 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. There are a spread of Sc(2)-Pt(1) bond distances ranging from 2.70-2.77 Å. Pt(1) is bonded in a 7-coordinate geometry to three equivalent Sc(1) and four equivalent Sc(2) atoms.
