The material structure described by NpN2 is Hydrophilite structured and crystallizes in the tetragonal P4_2/mnm space group. Np(1) is bonded to six equivalent N(1) atoms to form a mixture of corner and edge-sharing NpN6 octahedra. The corner-sharing octahedral tilt angles are 54°. N(1) is bonded in a trigonal planar geometry to three equivalent Np(1) atoms. is represented by the CIF file [CIF]
