Materials Data on Y3Si by Materials Project
Y3Si is Uranium Silicide structured and crystallizes in the cubic Pm-3m space group. The structure is three-dimensional. Y is bonded to eight equivalent Y and four equivalent Si atoms to form distorted YY8Si4 cuboctahedra that share corners with twelve equivalent YY8Si4 cuboctahedra, edges with eight equivalent SiY12 cuboctahedra, edges with sixteen equivalent YY8Si4 cuboctahedra, faces with four equivalent SiY12 cuboctahedra, and faces with fourteen equivalent YY8Si4 cuboctahedra. All Y–Y bond lengths are 3.30 Å. All Y–Si bond lengths are 3.30 Å. Si is bonded to twelve equivalent Y atoms to form SiY12 cuboctahedra that share corners with twelve equivalent SiY12 cuboctahedra, edges with twenty-four equivalent YY8Si4 cuboctahedra, faces with six equivalent SiY12 cuboctahedra, and faces with twelve equivalent YY8Si4 cuboctahedra.
