Materials Data on Mn3Ge by Materials Project

Abstract

Mn3Ge is alpha bismuth trifluoride structured and crystallizes in the cubic Fm-3m space group. The structure is three-dimensional. there are two inequivalent Mn sites. In the first Mn site, Mn is bonded to four equivalent Mn and four equivalent Ge atoms to form a mixture of distorted face, edge, and corner-sharing MnMn4Ge4 tetrahedra. All Mn–Mn bond lengths are 2.50 Å. All Mn–Ge bond lengths are 2.50 Å. In the second Mn site, Mn is bonded in a 8-coordinate geometry to eight equivalent Mn and six equivalent Ge atoms. All Mn–Ge bond lengths are 2.88 Å. Ge is bonded in a distorted body-centered cubic geometry to fourteen Mn atoms.
