Materials Data on Zr2Sb by Materials Project
Zr2Sb crystallizes in the tetragonal I4/mmm space group. The structure is three-dimensional. there are two inequivalent Zr sites. In the first Zr site, Zr is bonded in a 4-coordinate geometry to four equivalent Zr and four equivalent Sb atoms. All Zr–Zr bond lengths are 2.93 Å. All Zr–Sb bond lengths are 3.03 Å. In the second Zr site, Zr is bonded to five equivalent Sb atoms to form a mixture of distorted edge and corner-sharing ZrSb5 square pyramids. There are one shorter (2.94 Å) and four longer (2.99 Å) Zr–Sb bond lengths. Sb is bonded in a 9-coordinate geometry to nine Zr atoms.
