The crystal structure described by Co2U is Cubic Laves structured and crystallizes in the cubic Fd-3m space group. U(1) is bonded in a 16-coordinate geometry to four equivalent U(1) and twelve equivalent Co(1) atoms. Co(1) is bonded to six equivalent U(1) and six equivalent Co(1) atoms to form a mixture of edge, corner, and face-sharing CoU6Co6 cuboctahedra. is represented by the CIF file [CIF]
