KHoCo2 is Heusler structured and crystallizes in the trigonal R3m space group. K(1) is bonded in a distorted single-bond geometry to three equivalent Ho(1), one Co(1), and four equivalent Co(2) atoms. All K(1)-Ho(1) bond lengths are 3.19 Å. The K(1)-Co(1) bond length is 2.23 Å. There are three shorter (2.92 Å) and one longer (3.25 Å) K(1)-Co(2) bond length. Ho(1) is bonded in a 11-coordinate geometry to three equivalent K(1), four equivalent Co(1), and four equivalent Co(2) atoms. There are three shorter (2.92 Å) and one longer (3.25 Å) Ho(1)-Co(1) bond length. There are three shorter (2.92 Å) and one longer (3.25 Å) Ho(1)-Co(2) bond length. There are two inequivalent Co sites. In the first Co site, Co(1) is bonded in a distorted single-bond geometry to one K(1) and four equivalent Ho(1) atoms. In the second Co site, Co(2) is bonded in a distorted body-centered cubic geometry to four equivalent K(1) and four equivalent Ho(1) atoms.
