Mn(1) is bonded in a 10-coordinate geometry to two equivalent Ho(2), two equivalent Co(1), four equivalent Co(2), and four equivalent Co(3) atoms. There are three inequivalent Co sites. In the first Co site, Co(1) is bonded in a 14-coordinate geometry to one Ho(2), three equivalent Mn(1), one Co(1), three equivalent Co(3), and six equivalent Co(2) atoms. In the second Co site, Co(2) is bonded in a 12-coordinate geometry to one Ho(1), one Ho(2), two equivalent Mn(1), two equivalent Co(1), two equivalent Co(2), and four equivalent Co(3) atoms. In the third Co site, Co(3) is bonded in a 12-coordinate geometry to one Ho(2), two equivalent Ho(1), two equivalent Mn(1), one Co(1), two equivalent Co(3), and four equivalent Co(2) atoms.
