The compound described by Sn3Si is Uranium Silicide structured and crystallizes in the cubic Pm-3m space group. Sn(1) is bonded to eight equivalent Sn(1) and four equivalent Si(1) atoms to form distorted SnSi4Sn8 cuboctahedra that share corners with twelve equivalent Sn(1)Si4Sn8 cuboctahedra, edges with eight equivalent Si(1)Sn12 cuboctahedra, edges with sixteen equivalent Sn(1)Si4Sn8 cuboctahedra, faces with four equivalent Si(1)Sn12 cuboctahedra, and faces with fourteen equivalent Sn(1)Si4Sn8 cuboctahedra. Si(1) is bonded to twelve equivalent Sn(1) atoms to form distorted SiSn12 cuboctahedra that share corners with twelve equivalent Si(1)Sn12 cuboctahedra, edges with twenty-four equivalent Sn(1)Si4Sn8 cuboctahedra, faces with six equivalent Si(1)Sn12 cuboctahedra, and faces with twelve equivalent Sn(1)Si4Sn8 cuboctahedra. is represented by the CIF file [CIF]
