Mn2Fe4GeSi is Tungsten-derived structured and crystallizes in the trigonal R-3m space group. Mn(1) is bonded in a distorted body-centered cubic geometry to four Fe(1,1); four equivalent Fe(2); three equivalent Ge(1); and three equivalent Si(1) atoms. There are four inequivalent Fe sites. In the first Fe site, Fe(1) is bonded in a distorted body-centered cubic geometry to four equivalent Mn(1), one Ge(1), and three equivalent Si(1) atoms. In the second Fe site, Fe(2) is bonded in a body-centered cubic geometry to four equivalent Mn(1), three equivalent Ge(1), and one Si(1) atom. In the third Fe site, Fe(1) is bonded in a distorted body-centered cubic geometry to four equivalent Mn(1), one Ge(1), and three equivalent Si(1) atoms. In the fourth Fe site, Fe(1) is bonded in a distorted body-centered cubic geometry to four equivalent Mn(1), one Ge(1), and three equivalent Si(1) atoms. Ge(1) is bonded in a distorted body-centered cubic geometry to six equivalent Mn(1); two Fe(1,1); and six equivalent Fe(2) atoms. Si(1) is bonded in a distorted body-centered cubic geometry to six equivalent Mn(1); two equivalent Fe(2); and six Fe(1,1) atoms.
