Materials Data on Pu2SbTe2 by Materials Project
Pu2SbTe2 crystallizes in the tetragonal P-4m2 space group. The structure is three-dimensional. Pu+3.50+ is bonded to two equivalent Sb3- and five equivalent Te2- atoms to form a mixture of distorted edge, corner, and face-sharing PuSb2Te5 pentagonal bipyramids. Both Pu–Sb bond lengths are 3.25 Å. There are four shorter (3.10 Å) and one longer (3.19 Å) Pu–Te bond lengths. Sb3- is bonded in a 4-coordinate geometry to four equivalent Pu+3.50+ atoms. Te2- is bonded to five equivalent Pu+3.50+ atoms to form a mixture of distorted edge and corner-sharing TePu5 trigonal bipyramids.
