The material structure described by FeCo9 crystallizes in the tetragonal P4/mmm space group. Fe(1) is bonded in a distorted q6 geometry to two equivalent Co(1) and eight equivalent Co(2) atoms. There are two inequivalent Co sites. In the first Co site, Co(1) is bonded in a distorted q6 geometry to two equivalent Fe(1) and eight equivalent Co(2) atoms. In the second Co site, Co(2) is bonded in a 6-coordinate geometry to one Fe(1), one Co(1), and four equivalent Co(2) atoms. is represented by the CIF card [CIF]
