Materials Data on Mn2AlCo by Materials Project

Abstract

Mn2CoAl crystallizes in the cubic F-43m space group. The structure is three-dimensional. there are two inequivalent Mn sites. In the first Mn site, Mn is bonded in a 4-coordinate geometry to four equivalent Mn and four equivalent Co atoms. All Mn–Mn bond lengths are 2.49 Å. All Mn–Co bond lengths are 2.49 Å. In the second Mn site, Mn is bonded in a 8-coordinate geometry to four equivalent Mn, six equivalent Co, and four equivalent Al atoms. All Mn–Co bond lengths are 2.87 Å. All Mn–Al bond lengths are 2.49 Å. Co is bonded in a distorted body-centered cubic geometry to ten Mn and four equivalent Al atoms. All Co–Al bond lengths are 2.49 Å. Al is bonded in a distorted body-centered cubic geometry to four equivalent Mn and four equivalent Co atoms.
