Ho2RuCo crystallizes in the trigonal R3m space group. There are two inequivalent Ho sites. In the first Ho site, Ho(1) is bonded in a single-bond geometry to four equivalent Ru(1) and one Co(1) atom. There are three shorter (2.73 Å) and one longer (3.78 Å) Ho(1)-Ru(1) bond length. The Ho(1)-Co(1) bond length is 0.24 Å. In the second Ho site, Ho(2) is bonded in a 3-coordinate geometry to four equivalent Ru(1) atoms. There are three shorter (2.73 Å) and one longer (3.78 Å) Ho(2)-Ru(1) bond length. Ru(1) is bonded in a 11-coordinate geometry to four equivalent Ho(1), four equivalent Ho(2), and three equivalent Co(1) atoms. All Ru(1)-Co(1) bond lengths are 2.74 Å. Co(1) is bonded in a single-bond geometry to one Ho(1) and three equivalent Ru(1) atoms.
