The material described by K3U is Uranium Silicide structured and crystallizes in the cubic Pm-3m space group. K(1) is bonded to eight equivalent K(1) and four equivalent U(1) atoms to form distorted KK8U4 cuboctahedra that share corners with twelve equivalent K(1)K8U4 cuboctahedra, edges with eight equivalent U(1)K12 cuboctahedra, edges with sixteen equivalent K(1)K8U4 cuboctahedra, faces with four equivalent U(1)K12 cuboctahedra, and faces with fourteen equivalent K(1)K8U4 cuboctahedra. U(1) is bonded to twelve equivalent K(1) atoms to form UK12 cuboctahedra that share corners with twelve equivalent U(1)K12 cuboctahedra, edges with twenty-four equivalent K(1)K8U4 cuboctahedra, faces with six equivalent U(1)K12 cuboctahedra, and faces with twelve equivalent K(1)K8U4 cuboctahedra. is represented by the Crystallographic Information File (CIF) [CIF]
