Materials Data on Zr4Re2N by Materials Project
Zr4Re2N crystallizes in the cubic Fd-3m space group. The structure is three-dimensional. there are two inequivalent Zr sites. In the first Zr site, Zr is bonded in a 6-coordinate geometry to six equivalent Re atoms. All Zr–Re bond lengths are 2.71 Å. In the second Zr site, Zr is bonded in a distorted bent 150 degrees geometry to four equivalent Re and two equivalent N atoms. There are two shorter (2.97 Å) and two longer (3.25 Å) Zr–Re bond lengths. Both Zr–N bond lengths are 2.34 Å. Re is bonded in a 12-coordinate geometry to nine Zr and three equivalent Re atoms. All Re–Re bond lengths are 2.94 Å. N is bonded to six equivalent Zr atoms to form corner-sharing NZr6 octahedra. The corner-sharing octahedral tilt angles are 38°.
