ScPtIn crystallizes in the hexagonal P-62m space group. Sc(1) is bonded in a 11-coordinate geometry to one Pt(2), four equivalent Pt(1), and six equivalent In(1) atoms. There are two inequivalent Pt sites. In the first Pt site, Pt(1) is bonded in a 9-coordinate geometry to six equivalent Sc(1) and three equivalent In(1) atoms. In the second Pt site, Pt(2) is bonded in a 9-coordinate geometry to three equivalent Sc(1) and six equivalent In(1) atoms. In(1) is bonded in a 10-coordinate geometry to six equivalent Sc(1), two equivalent Pt(1), and two equivalent Pt(2) atoms.
ScPtIn crystallizes in the hexagonal P-62m space group. Sc(1) is bonded in a 11-coordinate geometry to one Pt(2), four equivalent Pt(1), and six equivalent In(1) atoms. The Sc(1)-Pt(2) bond length is 3.03 Å. All Sc(1)-Pt(1) bond lengths are 2.91 Å. There are two shorter (3.04 Å) and four longer (3.20 Å) Sc(1)-In(1) bond lengths. There are two inequivalent Pt sites. In the first Pt site, Pt(1) is bonded in a 9-coordinate geometry to six equivalent Sc(1) and three equivalent In(1) atoms. All Pt(1)-In(1) bond lengths are 2.79 Å. In the second Pt site, Pt(2) is bonded in a 9-coordinate geometry to three equivalent Sc(1) and six equivalent In(1) atoms. All Pt(2)-In(1) bond lengths are 2.72 Å. In(1) is bonded in a 10-coordinate geometry to six equivalent Sc(1), two equivalent Pt(1), and two equivalent Pt(2) atoms.
