Materials Data on Nb5Sb4 by Materials Project

Nb5Sb4 is Titanium telluride structured and crystallizes in the tetragonal I4/m space group. The structure is three-dimensional. there are two inequivalent Nb+2.40+ sites. In the first Nb+2.40+ site, Nb+2.40+ is bonded in a square co-planar geometry to four equivalent Sb3- atoms. All Nb–Sb bond lengths are 3.11 Å. In the second Nb+2.40+ site, Nb+2.40+ is bonded to five equivalent Sb3- atoms to form a mixture of distorted edge and corner-sharing NbSb5 trigonal bipyramids. There are three shorter (2.82 Å) and two longer (2.86 Å) Nb–Sb bond lengths. Sb3- is bonded in a 6-coordinate geometry to six Nb+2.40+ atoms.

Nb5Sb4 crystallizes in the tetragonal I4/m space group. The structure is three-dimensional. there are two inequivalent Nb+2.40+ sites. In the first Nb+2.40+ site, Nb+2.40+ is bonded in a 5-coordinate geometry to five equivalent Sb3- atoms. There are a spread of Nb–Sb bond distances ranging from 2.89–3.09 Å. In the second Nb+2.40+ site, Nb+2.40+ is bonded in a body-centered cubic geometry to eight equivalent Sb3- atoms. All Nb–Sb bond lengths are 2.88 Å. Sb3- is bonded in a 7-coordinate geometry to seven Nb+2.40+ atoms.
