KFeRhCo crystallizes in the trigonal R3m space group. K(1) is bonded in a 11-coordinate geometry to four equivalent Fe(1), three equivalent Rh(1), and four equivalent Co(1) atoms. There is one shorter (2.05 Å) and three longer (3.07 Å) K(1)-Fe(1) bond lengths. All K(1)-Rh(1) bond lengths are 2.73 Å. There is one shorter (2.44 Å) and three longer (2.88 Å) K(1)-Co(1) bond lengths. Fe(1) is bonded in a distorted single-bond geometry to four equivalent K(1) and three equivalent Rh(1) atoms. All Fe(1)-Rh(1) bond lengths are 2.73 Å. Rh(1) is bonded in a 7-coordinate geometry to three equivalent K(1), three equivalent Fe(1), and one Co(1) atom. The Rh(1)-Co(1) bond length is 2.05 Å. Co(1) is bonded in a distorted linear geometry to four equivalent K(1) and one Rh(1) atom.
