Materials Data on Zr3TaFe8 by Materials Project
Abstract
Zr3TaFe8 is Hexagonal Laves-derived structured and crystallizes in the trigonal R3m space group. The structure is three-dimensional. there are three inequivalent Zr sites. In the first Zr site, Zr is bonded in a 12-coordinate geometry to four Zr and twelve Fe atoms. There are three shorter (3.03 Å) and one longer (3.05 Å) Zr–Zr bond lengths. There are a spread of Zr–Fe bond distances ranging from 2.89–2.92 Å. In the second Zr site, Zr is bonded in a 12-coordinate geometry to three equivalent Zr, one Ta, and twelve Fe atoms. The Zr–Ta bond length is 3.00 Å. There are nine shorter (2.90 Å) and three longer (2.94 Å) Zr–Fe bond lengths. In the third Zr site, Zr is bonded in a 12-coordinate geometry to one Zr, three equivalent Ta, and twelve Fe atoms. All Zr–Ta bond lengths are 3.01 Å. There are three shorter (2.85 Å) and nine longer (2.89 Å) Zr–Fe bond lengths. Ta is bonded in a 12-coordinate geometry to four Zr and twelve Fe atoms. There are a spread of Ta–Fe bond distances ranging from 2.87–2.89 Å. There are four inequivalent Fe sites. In the first Fe site, Fe is bonded to four Zr, two equivalent Ta,more »

There are a spread of Fe–Fe bond distances ranging from 2.45–2.49 Å.
