Ba2MgYbRuO6 crystallizes in the orthorhombic Immm space group. Ba(1) is bonded in a 9-coordinate geometry to one Mg(1), four equivalent O(1), and four equivalent O(2) atoms. Mg(1) is bonded in a square co-planar geometry to two equivalent Ba(1) and four equivalent O(2) atoms. Yb(1) is bonded to two equivalent O(1) and four equivalent O(2) atoms to form YbO6 octahedra that share corners with six equivalent Ru(1)O6 octahedra. The corner-sharing octahedral tilt angles range from 0-5°. Ru(1) is bonded to two equivalent O(1) and four equivalent O(2) atoms to form RuO6 octahedra that share corners with six equivalent Yb(1)O6 octahedra. The corner-sharing octahedral tilt angles range from 0-5°. There are two inequivalent O sites. In the first O site, O(1) is bonded in a 6-coordinate geometry to four equivalent Ba(1), one Yb(1), and one Ru(1) atom. In the second O site, O(2) is bonded to two equivalent Ba(1), one Mg(1), one Yb(1), and one Ru(1) atom to form a mixture of distorted edge, corner, and face-sharing OBa2YbMgRu trigonal bipyramids.
