Materials Data on NpTe2 by Materials Project
NpTe2.0 crystallizes in the tetragonal P4/nmm space group. The structure is three-dimensional. Np4+ is bonded in a 9-coordinate geometry to nine Te2- atoms. There are a spread of Np–Te bond distances ranging from 3.24–3.26 Å. There are two inequivalent Te2- sites. In the first Te2- site, Te2- is bonded to five equivalent Np4+ atoms to form a mixture of distorted edge and corner-sharing TeNp5 trigonal bipyramids. In the second Te2- site, Te2- is bonded in a 8-coordinate geometry to four equivalent Np4+ and four equivalent Te2- atoms. All Te–Te bond lengths are 3.14 Å.
