Materials Data on Np2Te3 by Materials Project
Np2Te3 crystallizes in the tetragonal I-42d space group. The structure is three-dimensional. there are three inequivalent Np3+ sites. In the first Np3+ site, Np3+ is bonded to eight Te2- atoms to form a mixture of distorted face, edge, and corner-sharing NpTe8 hexagonal bipyramids. There are a spread of Np–Te bond distances ranging from 3.12–3.31 Å. In the second Np3+ site, Np3+ is bonded to eight Te2- atoms to form a mixture of distorted face, edge, and corner-sharing NpTe8 hexagonal bipyramids. There are a spread of Np–Te bond distances ranging from 3.13–3.33 Å. In the third Np3+ site, Np3+ is bonded to eight Te2- atoms to form a mixture of distorted face, edge, and corner-sharing NpTe8 hexagonal bipyramids. There are a spread of Np–Te bond distances ranging from 3.13–3.32 Å. There are three inequivalent Te2- sites. In the first Te2- site, Te2- is bonded in a 6-coordinate geometry to six Np3+ atoms. In the second Te2- site, Te2- is bonded to five Np3+ atoms to form a mixture of distorted face, edge, and corner-sharing TeNp5 square pyramids. In the third Te2- site, Te2- is bonded to five Np3+ atoms to form a mixture of distorted face, edge, and corner-sharing TeNp5 square pyramids.
