The crystal structure described by TaN2 is Hydrophilite-like structured and crystallizes in the cubic Pa-3 space group. Ta(1) is bonded to six equivalent N(1) atoms to form corner-sharing TaN6 octahedra. The corner-sharing octahedral tilt angles are 61°. N(1) is bonded in a trigonal planar geometry to three equivalent Ta(1) atoms. is represented by the CIF file [CIF]
