The structure described by Ba5Ru2O9(O2) crystallizes in the monoclinic C2/c space group. There are three inequivalent Ba sites. In the first Ba site, Ba(1) is bonded in a 9-coordinate geometry to two equivalent O(2), two equivalent O(4), two equivalent O(5), and three equivalent O(1) atoms. In the second Ba site, Ba(2) is bonded to two equivalent O(2), two equivalent O(4), two equivalent O(5), two equivalent O(6), and four equivalent O(3) atoms to form BaO12 cuboctahedra that share corners with six equivalent Ba(2)O12 cuboctahedra and faces with six equivalent Ru(1)O6 octahedra. In the third Ba site, Ba(3) is bonded in a 11-coordinate geometry to one O(6), two equivalent O(1), two equivalent O(2), two equivalent O(3), two equivalent O(4), and two equivalent O(5) atoms. Ru(1) is bonded to one O(2), one O(4), one O(5), one O(6), and two equivalent O(3) atoms to form RuO6 octahedra that share faces with three equivalent Ba(2)O12 cuboctahedra and  a faceface with one Ru(1)O6 octahedra. There are six inequivalent O sites. In the first O site, O(4) is bonded in a 6-coordinate geometry to one Ba(2), two equivalent Ba(1), two equivalent Ba(3), and one Ru(1) atom. In the second O site, O(5) is bonded in a 6-coordinate geometry to one Ba(2), two equivalent Ba(1), two equivalent Ba(3), and one Ru(1) atom. In the third O site, O(6) is bonded to two equivalent Ba(2), two equivalent Ba(3), and two equivalent Ru(1) atoms to form a mixture of distorted corner and face-sharing OBa4Ru2 octahedra. The corner-sharing octahedral tilt angles range from 7-60°. In the fourth O site, O(1) is bonded in a 6-coordinate geometry to two equivalent Ba(3), three equivalent Ba(1), and one O(1) atom. In the fifth O site, O(2) is bonded in a 6-coordinate geometry to one Ba(2), two equivalent Ba(1), two equivalent Ba(3), and one Ru(1) atom. In the sixth O site, O(3) is bonded to two equivalent Ba(2), two equivalent Ba(3), and two equivalent Ru(1) atoms to form a mixture of distorted corner and face-sharing OBa4Ru2 octahedra. The corner-sharing octahedral tilt angles range from 8-60°. is represented by the CIF card [CIF]
