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.
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. Both Y(1)-N(1) bond lengths are 2.25 Å. There are two shorter (3.17 Å) and two longer (3.24 Å) Y(1)-Te(2) bond lengths. 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. Both Y(2)-N(1) bond lengths are 2.21 Å. There is one shorter (3.04 Å) and one longer (3.11 Å) Y(2)-Te(1) bond length. Both Y(2)-Te(2) bond lengths are 3.52 Å. 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. There is one shorter (2.22 Å) and one longer (2.24 Å) Y(3)-N(1) bond length. There is one shorter (3.17 Å) and one longer (3.73 Å) Y(3)-Te(1) bond length. There are a spread of Y(3)-Te(2) bond distances ranging from 3.16-3.52 Å. N(1) is bonded to one Y(1), one Y(2), and two equivalent Y(3) atoms to form edge-sharing NY4 tetrahedra.
