The compound described by K3Ba 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 Ba(1) atoms to form KK8Ba4 cuboctahedra that share corners with twelve equivalent K(1)K8Ba4 cuboctahedra, edges with eight equivalent Ba(1)K12 cuboctahedra, edges with sixteen equivalent K(1)K8Ba4 cuboctahedra, faces with four equivalent Ba(1)K12 cuboctahedra, and faces with fourteen equivalent K(1)K8Ba4 cuboctahedra. Ba(1) is bonded to twelve equivalent K(1) atoms to form BaK12 cuboctahedra that share corners with twelve equivalent Ba(1)K12 cuboctahedra, edges with twenty-four equivalent K(1)K8Ba4 cuboctahedra, faces with six equivalent Ba(1)K12 cuboctahedra, and faces with twelve equivalent K(1)K8Ba4 cuboctahedra. is represented by the CIF file [CIF]
