Sc Sc Be Pt
BeSc2Pt crystallizes in the monoclinic Cm space group. Be(1) is bonded in a distorted single-bond geometry to one Sc(1) and one Pt(1) atom. The Be(1)-Sc(1) bond length is 1.98 Å. The Be(1)-Pt(1) bond length is 1.23 Å. There are two inequivalent Sc sites. In the first Sc site, Sc(1) is bonded in a 1-coordinate geometry to one Be(1) and one Sc(2) atom. The Sc(1)-Sc(2) bond length is 1.95 Å. In the second Sc site, Sc(2) is bonded in a 4-coordinate geometry to one Sc(1) and three equivalent Pt(1) atoms. There is one shorter (2.81 Å) and two longer (3.25 Å) Sc(2)-Pt(1) bond lengths. Pt(1) is bonded in a single-bond geometry to one Be(1) and three equivalent Sc(2) atoms.
