Fe2Co4GaSi is Tungsten-derived structured and crystallizes in the trigonal R-3m space group. Fe(1) is bonded in a distorted body-centered cubic geometry to four Co(1,1) and four equivalent Co(2) atoms. There are four inequivalent Co sites. In the first Co site, Co(1) is bonded in a distorted body-centered cubic geometry to four equivalent Fe(1), one Ga(1), and three equivalent Si(1) atoms. In the second Co site, Co(2) is bonded in a body-centered cubic geometry to four equivalent Fe(1), three equivalent Ga(1), and one Si(1) atom. In the third Co site, Co(1) is bonded in a distorted body-centered cubic geometry to four equivalent Fe(1), one Ga(1), and three equivalent Si(1) atoms. In the fourth Co site, Co(1) is bonded in a distorted body-centered cubic geometry to four equivalent Fe(1), one Ga(1), and three equivalent Si(1) atoms. Ga(1) is bonded in a distorted body-centered cubic geometry to two Co(1,1) and six equivalent Co(2) atoms. Si(1) is bonded in a distorted body-centered cubic geometry to two equivalent Co(2) and six Co(1,1) atoms.
