The crystal structure described by Al4N2Te3 crystallizes in the orthorhombic Pnma space group. There are three inequivalent Al sites. In the first Al site, Al(1) is bonded in a distorted L-shaped geometry to two equivalent N(1), one Te(1), and two equivalent Te(2) atoms. In the second Al site, Al(2) is bonded in a 4-coordinate geometry to two equivalent N(1) and two equivalent Te(1) atoms. In the third Al site, Al(3) is bonded in a distorted L-shaped geometry to two equivalent N(1) and two equivalent Te(2) atoms. N(1) is bonded in a 4-coordinate geometry to one Al(1), one Al(2), and two equivalent Al(3) atoms. There are two inequivalent Te sites. In the first Te site, Te(1) is bonded in a trigonal planar geometry to one Al(1) and two equivalent Al(2) atoms. In the second Te site, Te(2) is bonded in a trigonal planar geometry to one Al(1) and two equivalent Al(3) atoms. is represented by the Crystallographic Information File (CIF) [CIF]
