The crystal structure described by UN2 is Fluorite structured and crystallizes in the cubic Fm-3m space group. U(1) is bonded in a body-centered cubic geometry to eight equivalent N(1) atoms. N(1) is bonded to four equivalent U(1) atoms to form a mixture of edge and corner-sharing NU4 tetrahedra. is represented by the CIF file [CIF]
