Sc Ir Pt Pt
ScIrPt2 crystallizes in the monoclinic Cm space group. The structure is zero-dimensional and consists of two ScIrPt2 clusters. Sc(1) is bonded in a 2-coordinate geometry to two equivalent Pt(1) atoms. Both Sc(1)-Pt(1) bond lengths are 0.26 Å. Ir(1) is bonded in a 2-coordinate geometry to two equivalent Pt(1) atoms. Both Ir(1)-Pt(1) bond lengths are 0.14 Å. Pt(1) is bonded in a 3-coordinate geometry to one Sc(1), one Ir(1), and one Pt(1) atom. The Pt(1)-Pt(1) bond length is 0.10 Å.
