The material structure described by Nd4Te7 crystallizes in the tetragonal P4mm space group. There are four inequivalent Nd sites. In the first Nd site, Nd(1) is bonded in a 8-coordinate geometry to four equivalent Te(2) and four equivalent Te(4) atoms. In the second Nd site, Nd(2) is bonded in a 9-coordinate geometry to one Te(3), four equivalent Te(1), and four equivalent Te(5) atoms. In the third Nd site, Nd(3) is bonded in a 5-coordinate geometry to one Te(4) and four equivalent Te(1) atoms. In the fourth Nd site, Nd(4) is bonded in a 9-coordinate geometry to one Te(5), four equivalent Te(2), and four equivalent Te(3) atoms. There are five inequivalent Te sites. In the first Te site, Te(1) is bonded in a 4-coordinate geometry to two equivalent Nd(2) and two equivalent Nd(3) atoms. In the second Te site, Te(2) is bonded in a 8-coordinate geometry to two equivalent Nd(1), two equivalent Nd(4), and four equivalent Te(2) atoms. In the third Te site, Te(3) is bonded to one Nd(2) and four equivalent Nd(4) atoms to form a mixture of distorted corner and edge-sharing TeNd5 trigonal bipyramids. In the fourth Te site, Te(4) is bonded to one Nd(3) and four equivalent Nd(1) atoms to form a mixture of distorted corner and edge-sharing TeNd5 trigonal bipyramids. In the fifth Te site, Te(5) is bonded to one Nd(4) and four equivalent Nd(2) atoms to form a mixture of distorted corner and edge-sharing TeNd5 trigonal bipyramids. is represented by the Crystallographic Information File (CIF) [CIF]
