title: Materials Data on Mn4Cr(Co2Ge)5 by Materials Project

description: CrMn4(Co2Ge)5 is Tungsten-derived structured and crystallizes in the trigonal R-3m space group. The structure is three-dimensional. Cr is bonded in a distorted body-centered cubic geometry to eight Co and six equivalent Ge atoms. There are two shorter (2.47 Å) and six longer (2.48 Å) Cr–Co bond lengths. All Cr–Ge bond lengths are 2.86 Å. There are two inequivalent Mn sites. In the first Mn site, Mn is bonded in a distorted body-centered cubic geometry to eight Co and six Ge atoms. There are a spread of Mn–Co bond distances ranging from 2.46–2.49 Å. There are three shorter (2.86 Å) and three longer (2.88 Å) Mn–Ge bond lengths. In the second Mn site, Mn is bonded in a distorted body-centered cubic geometry to eight Co and six Ge atoms. There are two shorter (2.47 Å) and six longer (2.49 Å) Mn–Co bond lengths. All Mn–Ge bond lengths are 2.86 Å. There are nine inequivalent Co sites. In the first Co site, Co is bonded in a body-centered cubic geometry to three equivalent Cr, one Mn, and four equivalent Ge atoms. All Co–Cr bond lengths are 2.48 Å. The Co–Mn bond length is 2.49 Å. There are one shorter (2.44 Å) and three longer (2.49 Å) Co–Ge bond lengths. In the second Co site, Co is bonded in a body-centered cubic geometry to one Cr, three equivalent Mn, and four Ge atoms. There are one shorter (2.46 Å) and three longer (2.49 Å) Co–Ge bond lengths. In the third Co site, Co is bonded in a body-centered cubic geometry to four equivalent Mn and four Ge atoms. There are one shorter (2.46 Å) and three longer (2.49 Å) Co–Ge bond lengths. In the fourth Co site, Co is bonded in a body-centered cubic geometry to four Mn and four Ge atoms. There are one shorter (2.46 Å) and three longer (2.49 Å) Co–Ge bond lengths. In the fifth Co site, Co is bonded in a body-centered cubic geometry to three equivalent Cr, one Mn, and four equivalent Ge atoms. There are one shorter (2.44 Å) and three longer (2.49 Å) Co–Ge bond lengths. In the sixth Co site, Co is bonded in a body-centered cubic geometry to four Mn and four Ge atoms.
