SrScPt4 crystallizes in the trigonal R3m space group. Sr(1) is bonded in a distorted rectangular see-saw-like geometry to one Sc(1) and three equivalent Pt(1) atoms. The Sr(1)-Sc(1) bond length is 0.95 Å. All Sr(1)-Pt(1) bond lengths are 0.82 Å. Sc(1) is bonded in a single-bond geometry to one Sr(1) and three equivalent Pt(2) atoms. All Sc(1)-Pt(2) bond lengths are 3.80 Å. There are two inequivalent Pt sites. In the first Pt site, Pt(2) is bonded in a 6-coordinate geometry to three equivalent Sc(1) and three equivalent Pt(1) atoms. All Pt(2)-Pt(1) bond lengths are 0.63 Å. In the second Pt site, Pt(1) is bonded in a 4-coordinate geometry to one Sr(1), one Pt(2), and two equivalent Pt(1) atoms. Both Pt(1)-Pt(1) bond lengths are 0.36 Å.
