Tb3NTe3 crystallizes in the monoclinic P2_1/c space group. There are three inequivalent Tb sites. In the first Tb site, Tb(1) is bonded in a distorted L-shaped geometry to two equivalent N(1), one Te(1), one Te(3), and two equivalent Te(2) atoms. In the second Tb site, Tb(2) is bonded in a distorted single-bond geometry to one N(1), one Te(2), two equivalent Te(1), and two equivalent Te(3) atoms. In the third Tb site, Tb(3) is bonded in a distorted single-bond geometry to one N(1), one Te(1), two equivalent Te(2), and two equivalent Te(3) atoms. N(1) is bonded to one Tb(2), one Tb(3), and two equivalent Tb(1) atoms to form edge-sharing NTb4 tetrahedra. There are three inequivalent Te sites. In the first Te site, Te(1) is bonded in a 4-coordinate geometry to one Tb(1), one Tb(3), and two equivalent Tb(2) atoms. In the second Te site, Te(2) is bonded in a 5-coordinate geometry to one Tb(2), two equivalent Tb(1), and two equivalent Tb(3) atoms. In the third Te site, Te(3) is bonded in a distorted pentagonal planar geometry to one Tb(1), two equivalent Tb(2), and two equivalent Tb(3) atoms.
