Hf Sc Sc Pt
Sc2HfPt crystallizes in the monoclinic Cm space group. There are two inequivalent Sc sites. In the first Sc site, Sc(1) is bonded in a single-bond geometry to one Hf(1) and one Pt(1) atom. The Sc(1)-Hf(1) bond length is 1.25 Å. The Sc(1)-Pt(1) bond length is 3.75 Å. In the second Sc site, Sc(2) is bonded in a distorted single-bond geometry to one Hf(1) and one Pt(1) atom. The Sc(2)-Hf(1) bond length is 1.55 Å. The Sc(2)-Pt(1) bond length is 3.02 Å. Hf(1) is bonded in a 2-coordinate geometry to one Sc(1), one Sc(2), and three equivalent Pt(1) atoms. There is one shorter (3.14 Å) and two longer (3.73 Å) Hf(1)-Pt(1) bond lengths. Pt(1) is bonded in a 9-coordinate geometry to one Sc(1), one Sc(2), three equivalent Hf(1), and four equivalent Pt(1) atoms. All Pt(1)-Pt(1) bond lengths are 3.36 Å.
