The structure described by Ba2MgHoRuO6 crystallizes in the monoclinic Cm space group. There are two inequivalent Ba sites. In the first Ba site, Ba(1) is bonded in a distorted q6 geometry to one O(2), two equivalent O(1), two equivalent O(3), and four equivalent O(4) atoms. In the second Ba site, Ba(2) is bonded in a 3-coordinate geometry to one O(3) and two equivalent O(4) atoms. Mg(1) is bonded in a distorted trigonal non-coplanar geometry to one O(3) and two equivalent O(4) atoms. Ho(1) is bonded to one O(2), one O(3), two equivalent O(1), and two equivalent O(4) atoms to form distorted HoO6 octahedra that share corners with six equivalent Ru(1)O6 octahedra. The corner-sharing octahedral tilt angles range from 3-11°. Ru(1) is bonded to one O(2), one O(3), two equivalent O(1), and two equivalent O(4) atoms to form RuO6 octahedra that share corners with six equivalent Ho(1)O6 octahedra. The corner-sharing octahedral tilt angles range from 3-11°. There are four inequivalent O sites. In the first O site, O(1) is bonded in a 2-coordinate geometry to one Ba(1), one Ho(1), and one Ru(1) atom. In the second O site, O(2) is bonded in a distorted linear geometry to one Ba(1), one Ho(1), and one Ru(1) atom. In the third O site, O(3) is bonded in a 6-coordinate geometry to one Ba(2), two equivalent Ba(1), one Mg(1), one Ho(1), and one Ru(1) atom. In the fourth O site, O(4) is bonded in a 6-coordinate geometry to one Ba(2), two equivalent Ba(1), one Mg(1), one Ho(1), and one Ru(1) atom. is represented by the CIF card [CIF]
