Title: Materials Data on ZrMnAl by Materials Project

Abstract

ZrMnAl is Hexagonal Laves-derived structured and crystallizes in the orthorhombic Amm2 space group. The structure is three-dimensional. there are six inequivalent Zr sites. In the first Zr site, Zr is bonded in a 12-coordinate geometry to four Zr, five Mn, and seven Al atoms. There are a spread of Zr–Zr bond distances ranging from 3.15–3.27 Å. There are three shorter (2.96 Å) and two longer (3.09 Å) Zr–Mn bond lengths. There are five shorter (3.04 Å) and two longer (3.05 Å) Zr–Al bond lengths. In the second Zr site, Zr is bonded in a 12-coordinate geometry to four Zr, seven Mn, and five Al atoms. There are one shorter (3.02 Å) and two longer (3.20 Å) Zr–Zr bond lengths. There are a spread of Zr–Mn bond distances ranging from 2.97–3.08 Å. There are a spread of Zr–Al bond distances ranging from 2.95–3.09 Å. In the third Zr site, Zr is bonded in a 12-coordinate geometry to four Zr, seven Mn, and five Al atoms. There are one shorter (3.15 Å) and two longer (3.20 Å) Zr–Zr bond lengths. There are a spread of Zr–Mn bond distances ranging from 2.97–3.08 Å. There are a spread of Zr–Al bond distances ranging frommore » 2.95–3.09 Å.
