The crystal structure described by Pr4N2Te3 crystallizes in the orthorhombic Pnma space group. There are three inequivalent Pr sites. In the first Pr site, Pr(1) is bonded in a distorted L-shaped geometry to two equivalent N(1), two equivalent Te(1), and three equivalent Te(2) atoms. In the second Pr site, Pr(2) is bonded in a 2-coordinate geometry to two equivalent N(1) and four equivalent Te(2) atoms. In the third Pr site, Pr(3) is bonded in a 2-coordinate geometry to two equivalent N(1), two equivalent Te(1), and two equivalent Te(2) atoms. N(1) is bonded to one Pr(2), one Pr(3), and two equivalent Pr(1) atoms to form NPr4 tetrahedra that share corners with four equivalent Te(1)Pr6 octahedra,  an edgeedge with one Te(1)Pr6 octahedra, and edges with two equivalent N(1)Pr4 tetrahedra. The corner-sharing octahedral tilt angles range from 20-67°. There are two inequivalent Te sites. In the first Te site, Te(1) is bonded to two equivalent Pr(3) and four equivalent Pr(1) atoms to form TePr6 octahedra that share corners with eight equivalent N(1)Pr4 tetrahedra, edges with two equivalent N(1)Pr4 tetrahedra, and faces with two equivalent Te(1)Pr6 octahedra. In the second Te site, Te(2) is bonded in a 6-coordinate geometry to one Pr(3), two equivalent Pr(2), and three equivalent Pr(1) atoms. is represented by the CIF file [CIF]
