NpTe2.0 crystallizes in the tetragonal P4/nmm space group. Np(1) is bonded in a 9-coordinate geometry to four equivalent Te(2) and five equivalent Te(1) atoms. There are two inequivalent Te sites. In the first Te site, Te(1) is bonded to five equivalent Np(1) atoms to form a mixture of distorted corner and edge-sharing TeNp5 trigonal bipyramids. In the second Te site, Te(2) is bonded in a 8-coordinate geometry to four equivalent Np(1) and four equivalent Te(2) atoms.
NpTe2.0 crystallizes in the tetragonal P4/nmm space group. Np(1) is bonded in a 9-coordinate geometry to four equivalent Te(2) and five equivalent Te(1) atoms. All Np(1)-Te(2) bond lengths are 3.33 Å. There are four shorter (3.28 Å) and one longer (3.29 Å) Np(1)-Te(1) bond length. There are two inequivalent Te sites. In the first Te site, Te(1) is bonded to five equivalent Np(1) atoms to form a mixture of distorted corner and edge-sharing TeNp5 trigonal bipyramids. In the second Te site, Te(2) is bonded in a 8-coordinate geometry to four equivalent Np(1) and four equivalent Te(2) atoms. All Te(2)-Te(2) bond lengths are 3.17 Å.
