Materials Data on Pr2Sb by Materials Project
Pr2Sb crystallizes in the tetragonal I4/mmm space group. The structure is three-dimensional. there are two inequivalent Pr sites. In the first Pr site, Pr is bonded in a 4-coordinate geometry to four equivalent Sb atoms. All Pr–Sb bond lengths are 3.39 Å. In the second Pr site, Pr is bonded to five equivalent Sb atoms to form a mixture of distorted edge and corner-sharing PrSb5 trigonal bipyramids. There are one shorter (3.27 Å) and four longer (3.35 Å) Pr–Sb bond lengths. Sb is bonded in a 9-coordinate geometry to nine Pr atoms.
