Pt3In is Uranium Silicide structured and crystallizes in the cubic Pm-3m space group. Pt(1) is bonded to eight equivalent Pt(1) and four equivalent In(1) atoms to form distorted PtIn4Pt8 cuboctahedra that share corners with twelve equivalent Pt(1)In4Pt8 cuboctahedra, edges with eight equivalent In(1)Pt12 cuboctahedra, edges with sixteen equivalent Pt(1)In4Pt8 cuboctahedra, faces with four equivalent In(1)Pt12 cuboctahedra, and faces with fourteen equivalent Pt(1)In4Pt8 cuboctahedra. In(1) is bonded to twelve equivalent Pt(1) atoms to form InPt12 cuboctahedra that share corners with twelve equivalent In(1)Pt12 cuboctahedra, edges with twenty-four equivalent Pt(1)In4Pt8 cuboctahedra, faces with six equivalent In(1)Pt12 cuboctahedra, and faces with twelve equivalent Pt(1)In4Pt8 cuboctahedra.
