FeCo2Zn crystallizes in the monoclinic Cm space group. Fe(1) is bonded in a 6-coordinate geometry to four equivalent Fe(1), one Co(1), and one Co(2) atom. All Fe(1)-Fe(1) bond lengths are 2.52 Å. The Fe(1)-Co(1) bond length is 2.62 Å. The Fe(1)-Co(2) bond length is 2.84 Å. There are two inequivalent Co sites. In the first Co site, Co(1) is bonded in a single-bond geometry to one Fe(1) and one Zn(1) atom. The Co(1)-Zn(1) bond length is 1.30 Å. In the second Co site, Co(2) is bonded in a single-bond geometry to one Fe(1) and one Zn(1) atom. The Co(2)-Zn(1) bond length is 1.30 Å. Zn(1) is bonded in an L-shaped geometry to one Co(1) and one Co(2) atom.
