Materials Data on Mn4FeGe3 by Materials Project
Mn4FeGe3 crystallizes in the monoclinic C2/m space group. The structure is three-dimensional. there are three inequivalent Mn sites. In the first Mn site, Mn is bonded in a 8-coordinate geometry to two equivalent Fe and six Ge atoms. Both Mn–Fe bond lengths are 2.47 Å. All Mn–Ge bond lengths are 2.53 Å. In the second Mn site, Mn is bonded in a 5-coordinate geometry to five Ge atoms. There are a spread of Mn–Ge bond distances ranging from 2.45–2.69 Å. In the third Mn site, Mn is bonded in a 5-coordinate geometry to five Ge atoms. There are a spread of Mn–Ge bond distances ranging from 2.45–2.70 Å. Fe is bonded in a 8-coordinate geometry to two equivalent Mn and six Ge atoms. All Fe–Ge bond lengths are 2.50 Å. There are two inequivalent Ge sites. In the first Ge site, Ge is bonded in a 9-coordinate geometry to seven Mn and two equivalent Fe atoms. In the second Ge site, Ge is bonded in a 9-coordinate geometry to seven Mn and two equivalent Fe atoms.
