Materials Data on Sn3Se by Materials Project
Sn3Se 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 Se atoms to form distorted SnSn8Se4 cuboctahedra that share corners with twelve equivalent SnSn8Se4 cuboctahedra, edges with eight equivalent SeSn12 cuboctahedra, edges with sixteen equivalent SnSn8Se4 cuboctahedra, faces with four equivalent SeSn12 cuboctahedra, and faces with fourteen equivalent SnSn8Se4 cuboctahedra. All Sn–Sn bond lengths are 3.35 Å. All Sn–Se bond lengths are 3.35 Å. Se is bonded to twelve equivalent Sn atoms to form distorted SeSn12 cuboctahedra that share corners with twelve equivalent SeSn12 cuboctahedra, edges with twenty-four equivalent SnSn8Se4 cuboctahedra, faces with six equivalent SeSn12 cuboctahedra, and faces with twelve equivalent SnSn8Se4 cuboctahedra.
