The crystal structure described by (FeCo)3Ge2 crystallizes in the trigonal R3m space group. There are three inequivalent Fe sites. In the first Fe site, Fe(1) is bonded in a body-centered cubic geometry to one Co(1), three equivalent Co(2), one Ge(1), and three equivalent Ge(2) atoms. In the second Fe site, Fe(2) is bonded in a distorted body-centered cubic geometry to one Co(2), three equivalent Co(1), three equivalent Co(3), one Ge(1), and three equivalent Ge(2) atoms. In the third Fe site, Fe(3) is bonded in a 8-coordinate geometry to one Co(1), three equivalent Co(2), three equivalent Co(3), one Ge(2), and three equivalent Ge(1) atoms. There are three inequivalent Co sites. In the first Co site, Co(1) is bonded in a 14-coordinate geometry to one Fe(1), one Fe(3), three equivalent Fe(2), three equivalent Co(3), three equivalent Ge(1), and three equivalent Ge(2) atoms. In the second Co site, Co(2) is bonded in a 14-coordinate geometry to one Fe(2), three equivalent Fe(1), three equivalent Fe(3), one Co(3), three equivalent Ge(1), and three equivalent Ge(2) atoms. In the third Co site, Co(3) is bonded in a 14-coordinate geometry to three equivalent Fe(2), three equivalent Fe(3), one Co(2), three equivalent Co(1), one Ge(2), and three equivalent Ge(1) atoms. There are two inequivalent Ge sites. In the first Ge site, Ge(1) is bonded in a body-centered cubic geometry to one Fe(1), one Fe(2), three equivalent Fe(3), three equivalent Co(1), three equivalent Co(2), and three equivalent Co(3) atoms.
