Materials Data on Mn4Ga3Co8Ge by Materials Project
Mn4Co8Ga3Ge is Tungsten-derived structured and crystallizes in the trigonal R-3m space group. The structure is three-dimensional. 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 Ga atoms. There are a spread of Mn–Co bond distances ranging from 2.47–2.50 Å. All Mn–Ga bond lengths are 2.86 Å. In the second Mn site, Mn is bonded in a distorted body-centered cubic geometry to eight Co, three equivalent Ga, and three equivalent Ge atoms. There are a spread of Mn–Co bond distances ranging from 2.44–2.49 Å. All Mn–Ga bond lengths are 2.85 Å. All Mn–Ge bond lengths are 2.87 Å. There are five inequivalent Co sites. In the first Co site, Co is bonded in a body-centered cubic geometry to four equivalent Mn and four Ga atoms. There are one shorter (2.47 Å) and three longer (2.48 Å) Co–Ga bond lengths. In the second Co site, Co is bonded in a distorted body-centered cubic geometry to four Mn and four Ga atoms. There are three shorter (2.47 Å) and one longer (2.49 Å) Co–Ga bond lengths. In the third Co site, Co is bonded in a distorted body-centered cubic geometry to four equivalent Mn, one Ga, and three equivalent Ge atoms. The Co–Ga bond length is 2.51 Å. All Co–Ge bond lengths are 2.47 Å. In the fourth Co site, Co is bonded in a body-centered cubic geometry to four Mn, three equivalent Ga, and one Ge atom. All Co–Ga bond lengths are 2.48 Å. The Co–Ge bond length is 2.46 Å. In the fifth Co site, Co is bonded in a body-centered cubic geometry to four equivalent Mn and four Ga atoms. There are one shorter (2.47 Å) and three longer (2.48 Å) Co–Ga bond lengths. There are two inequivalent Ga sites. In the first Ga site, Ga is bonded in a distorted body-centered cubic geometry to six Mn and eight Co atoms. In the second Ga site, Ga is bonded in a distorted body-centered cubic geometry to six equivalent Mn and eight Co atoms. Ge is bonded in a distorted body-centered cubic geometry to six equivalent Mn and eight Co atoms.
