Y3NTe3 crystallizes in the monoclinic P2_1/c space group. There are three inequivalent Y sites. In the first Y site, Y(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 Y site, Y(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 Y site, Y(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 Y(2), one Y(3), and two equivalent Y(1) atoms to form edge-sharing NY4 tetrahedra. There are three inequivalent Te sites. In the first Te site, Te(1) is bonded in a distorted rectangular see-saw-like geometry to one Y(1), one Y(3), and two equivalent Y(2) atoms. In the second Te site, Te(2) is bonded in a 5-coordinate geometry to one Y(2), two equivalent Y(1), and two equivalent Y(3) atoms. In the third Te site, Te(3) is bonded in a distorted pentagonal planar geometry to one Y(1), two equivalent Y(2), and two equivalent Y(3) atoms.
