Sc Sc Pt Cl
Sc2PtCl crystallizes in the monoclinic Cm space group. There are two inequivalent Sc sites. In the first Sc site, Sc(1) is bonded in a 8-coordinate geometry to one Sc(2), four equivalent Sc(1), and three equivalent Pt(1) atoms. The Sc(1)-Sc(2) bond length is 2.20 Å. All Sc(1)-Sc(1) bond lengths are 3.23 Å. There is one shorter (3.25 Å) and two longer (3.60 Å) Sc(1)-Pt(1) bond lengths. In the second Sc site, Sc(2) is bonded in a 5-coordinate geometry to one Sc(1) and four equivalent Cl(1) atoms. There are a spread of Sc(2)-Cl(1) bond distances ranging from 2.29-3.16 Å. Pt(1) is bonded in a single-bond geometry to three equivalent Sc(1) and one Cl(1) atom. The Pt(1)-Cl(1) bond length is 1.28 Å. Cl(1) is bonded in a 2-coordinate geometry to four equivalent Sc(2) and one Pt(1) atom.
