The compound described by U3Si is Uranium Silicide structured and crystallizes in the cubic Pm-3m space group. U(1) is bonded to eight equivalent U(1) and four equivalent Si(1) atoms to form distorted UU8Si4 cuboctahedra that share corners with twelve equivalent U(1)U8Si4 cuboctahedra, edges with eight equivalent Si(1)U12 cuboctahedra, edges with sixteen equivalent U(1)U8Si4 cuboctahedra, faces with four equivalent Si(1)U12 cuboctahedra, and faces with fourteen equivalent U(1)U8Si4 cuboctahedra. Si(1) is bonded to twelve equivalent U(1) atoms to form SiU12 cuboctahedra that share corners with twelve equivalent Si(1)U12 cuboctahedra, edges with twenty-four equivalent U(1)U8Si4 cuboctahedra, faces with six equivalent Si(1)U12 cuboctahedra, and faces with twelve equivalent U(1)U8Si4 cuboctahedra. is represented by the CIF card [CIF]
