Sc3PtIn crystallizes in the trigonal R3m space group. Sc(1) is bonded in a 1-coordinate geometry to one Pt(1) and two equivalent In(1) atoms. The Sc(1)-Pt(1) bond length is 2.93 Å. There is one shorter (2.07 Å) and one longer (3.13 Å) Sc(1)-In(1) bond length. Pt(1) is bonded in a 3-coordinate geometry to three equivalent Sc(1) atoms. In(1) is bonded to six equivalent Sc(1) atoms to form distorted corner-sharing InSc6 octahedra. The corner-sharing octahedra are not tilted.
