ScRhPt crystallizes in the trigonal R3m space group. Sc(1) is bonded to three equivalent Rh(1) and three equivalent Pt(1) atoms to form distorted ScPt3Rh3 octahedra that share corners with three equivalent Pt(1)Sc3Rh tetrahedra and edges with six equivalent Sc(1)Pt3Rh3 octahedra. All Sc(1)-Rh(1) bond lengths are 3.20 Å. All Sc(1)-Pt(1) bond lengths are 2.69 Å. Rh(1) is bonded in a distorted single-bond geometry to three equivalent Sc(1) and one Pt(1) atom. The Rh(1)-Pt(1) bond length is 0.50 Å. Pt(1) is bonded to three equivalent Sc(1) and one Rh(1) atom to form PtSc3Rh tetrahedra that share corners with three equivalent Sc(1)Pt3Rh3 octahedra and corners with six equivalent Pt(1)Sc3Rh tetrahedra. The corner-sharing octahedral tilt angles are 51°.
