K3Cd 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 Cd(1) atoms to form distorted KK8Cd4 cuboctahedra that share corners with twelve equivalent K(1)K8Cd4 cuboctahedra, edges with eight equivalent Cd(1)K12 cuboctahedra, edges with sixteen equivalent K(1)K8Cd4 cuboctahedra, faces with four equivalent Cd(1)K12 cuboctahedra, and faces with fourteen equivalent K(1)K8Cd4 cuboctahedra. Cd(1) is bonded to twelve equivalent K(1) atoms to form CdK12 cuboctahedra that share corners with twelve equivalent Cd(1)K12 cuboctahedra, edges with twenty-four equivalent K(1)K8Cd4 cuboctahedra, faces with six equivalent Cd(1)K12 cuboctahedra, and faces with twelve equivalent K(1)K8Cd4 cuboctahedra.
