Materials Data on ErZrSb by Materials Project
ErZrSb crystallizes in the tetragonal I4/mmm space group. The structure is three-dimensional. Er is bonded to five equivalent Sb atoms to form a mixture of distorted edge and corner-sharing ErSb5 trigonal bipyramids. There are four shorter (3.09 Å) and one longer (3.13 Å) Er–Sb bond lengths. Zr is bonded in a distorted square co-planar geometry to four equivalent Sb atoms. All Zr–Sb bond lengths are 3.08 Å. Sb is bonded in a 9-coordinate geometry to five equivalent Er and four equivalent Zr atoms.
