Tb2N3 is Spinel-derived structured and crystallizes in the cubic Ia-3 space group. There are two inequivalent Tb sites. In the first Tb site, Tb(1) is bonded to six equivalent N(1) atoms to form a mixture of distorted corner and edge-sharing TbN6 octahedra. The corner-sharing octahedral tilt angles are 58°. In the second Tb site, Tb(2) is bonded to six equivalent N(1) atoms to form a mixture of distorted corner and edge-sharing TbN6 octahedra. The corner-sharing octahedral tilt angles range from 56-58°. N(1) is bonded to one Tb(1) and three equivalent Tb(2) atoms to form a mixture of corner and edge-sharing NTb4 tetrahedra.

In the first Tb site, Tb(1) is bonded to six equivalent N(1) atoms to form a mixture of distorted corner and edge-sharing TbN6 octahedra. The corner-sharing octahedral tilt angles are 58°. All Tb(1)-N(1) bond lengths are 2.37 Å. In the second Tb site, Tb(2) is bonded to six equivalent N(1) atoms to form a mixture of distorted corner and edge-sharing TbN6 octahedra. The corner-sharing octahedral tilt angles range from 56-58°. There are a spread of Tb(2)-N(1) bond distances ranging from 2.34-2.42 Å. N(1) is bonded to one Tb(1) and three equivalent Tb(2) atoms to form a mixture of corner and edge-sharing NTb4 tetrahedra.
