The material structure described by U2N2Sb is alpha bismuth trifluoride-derived structured and crystallizes in the tetragonal I4/mmm space group. U(1) is bonded in a 4-coordinate geometry to four equivalent Sb(1) and four equivalent N(1) atoms. Sb(1) is bonded in a body-centered cubic geometry to eight equivalent U(1) atoms. N(1) is bonded to four equivalent U(1) atoms to form a mixture of corner and edge-sharing NU4 tetrahedra. is represented by the CIF card [CIF]
