ScPtAg3 is (Cubic) Perovskite structured and crystallizes in the trigonal R3m space group. Sc(1) is bonded to twelve equivalent Ag(1) atoms to form ScAg12 cuboctahedra that share corners with twelve equivalent Sc(1)Ag12 cuboctahedra, faces with six equivalent Sc(1)Ag12 cuboctahedra, and faces with eight equivalent Pt(1)Ag6 octahedra. There are a spread of Sc(1)-Ag(1) bond distances ranging from 3.43-3.70 Å. Pt(1) is bonded to six equivalent Ag(1) atoms to form PtAg6 octahedra that share corners with six equivalent Pt(1)Ag6 octahedra and faces with eight equivalent Sc(1)Ag12 cuboctahedra. The corner-sharing octahedra are not tilted. There are three shorter (2.42 Å) and three longer (2.61 Å) Pt(1)-Ag(1) bond lengths. Ag(1) is bonded in a distorted linear geometry to four equivalent Sc(1) and two equivalent Pt(1) atoms.
