The crystal structure described by Fe4Co8GaSi3 is Tungsten-derived structured and crystallizes in the trigonal R-3m space group. There are two inequivalent Fe sites. In the first Fe site, Fe(1) is bonded in a distorted body-centered cubic geometry to one Co(4); three equivalent Co(2); and four Co(1,1) atoms. In the second Fe site, Fe(2) is bonded in a distorted body-centered cubic geometry to one Co(2); three equivalent Co(4); and four Co(3,3) atoms. There are eight inequivalent Co sites. In the first Co site, Co(1) is bonded in a body-centered cubic geometry to four equivalent Fe(1), one Si(1), and three equivalent Si(2) atoms. In the second Co site, Co(2) is bonded in a body-centered cubic geometry to one Fe(2), three equivalent Fe(1), one Si(2), and three equivalent Si(1) atoms.
