Materials Data on Zr5Re24 by Materials Project

Zr5Re24 crystallizes in the cubic I-43m space group. The structure is three-dimensional. there are two inequivalent Zr sites. In the first Zr site, Zr is bonded in a 12-coordinate geometry to four equivalent Zr and twelve equivalent Re atoms. All Zr–Zr bond lengths are 3.15 Å. All Zr–Re bond lengths are 3.07 Å. In the second Zr site, Zr is bonded in a 3-coordinate geometry to one Zr and fifteen Re atoms. There are a spread of Zr–Re bond distances ranging from 2.80–3.25 Å. There are two inequivalent Re sites. In the first Re site, Re is bonded in a 1-coordinate geometry to two equivalent Zr and eleven Re atoms. There are a spread of Re–Re bond distances ranging from 2.55–2.94 Å. In the second Re site, Re is bonded to four Zr and eight Re atoms to form a mixture of distorted face, edge, and corner-sharing ReZr4Re8 cuboctahedra. There are one shorter (2.53 Å) and two longer (2.70 Å) Re–Re bond lengths.
