The material structure described by Y4N2Te3 crystallizes in the orthorhombic Pnma 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) and four equivalent Te(2) atoms. In the second Y site, Y(2) is bonded in a distorted L-shaped geometry to two equivalent N(1), two equivalent Te(1), and two equivalent Te(2) atoms. In the third Y site, Y(3) is bonded in a distorted L-shaped geometry to two equivalent N(1), two equivalent Te(1), and three equivalent Te(2) atoms. N(1) is bonded to one Y(1), one Y(2), and two equivalent Y(3) atoms to form edge-sharing NY4 tetrahedra. There are two inequivalent Te sites. In the first Te site, Te(1) is bonded in a 6-coordinate geometry to two equivalent Y(2) and four equivalent Y(3) atoms. In the second Te site, Te(2) is bonded in a 6-coordinate geometry to one Y(2), two equivalent Y(1), and three equivalent Y(3) atoms. is represented by the Crystallographic Information File (CIF) [CIF]
