Materials Data on SiSn3 by Materials Project
Sn3Si is Uranium Silicide structured and crystallizes in the cubic Pm-3m space group. The structure is three-dimensional. Sn is bonded to eight equivalent Sn and four equivalent Si atoms to form distorted SnSi4Sn8 cuboctahedra that share corners with twelve equivalent SnSi4Sn8 cuboctahedra, edges with eight equivalent SiSn12 cuboctahedra, edges with sixteen equivalent SnSi4Sn8 cuboctahedra, faces with four equivalent SiSn12 cuboctahedra, and faces with fourteen equivalent SnSi4Sn8 cuboctahedra. All Sn–Sn bond lengths are 3.29 Å. All Sn–Si bond lengths are 3.29 Å. Si is bonded to twelve equivalent Sn atoms to form distorted SiSn12 cuboctahedra that share corners with twelve equivalent SiSn12 cuboctahedra, edges with twenty-four equivalent SnSi4Sn8 cuboctahedra, faces with six equivalent SiSn12 cuboctahedra, and faces with twelve equivalent SnSi4Sn8 cuboctahedra.
