The material described by CrFeCo4Al2 is Tungsten-derived structured and crystallizes in the trigonal R-3m space group. Cr(1) is bonded in a body-centered cubic geometry to two equivalent Co(2) and six equivalent Co(1) atoms. Fe(1) is bonded in a distorted body-centered cubic geometry to two Co(1,1); six equivalent Co(2); and six equivalent Al(1) atoms. There are four inequivalent Co sites. In the first Co site, Co(1) is bonded in a body-centered cubic geometry to three equivalent Cr(1), one Fe(1), and four equivalent Al(1) atoms. In the second Co site, Co(2) is bonded in a body-centered cubic geometry to one Cr(1), three equivalent Fe(1), and four equivalent Al(1) atoms. In the third Co site, Co(1) is bonded in a body-centered cubic geometry to three equivalent Cr(1), one Fe(1), and four equivalent Al(1) atoms. In the fourth Co site, Co(1) is bonded in a body-centered cubic geometry to three equivalent Cr(1), one Fe(1), and four equivalent Al(1) atoms. Al(1) is bonded in a body-centered cubic geometry to three equivalent Fe(1), four equivalent Co(1), and four equivalent Co(2) atoms. is represented by the Crystallographic Information File (CIF) [CIF]
