The material described by Ba5Ru2O10 crystallizes in the hexagonal P6_3/mmc space group. There are three inequivalent Ba sites. In the first Ba site, Ba(1) is bonded in a 6-coordinate geometry to six equivalent O(2) atoms. In the second Ba site, Ba(2) is bonded to six equivalent O(2) and six 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 10-coordinate geometry to one O(1), three equivalent O(3), and six equivalent O(2) atoms. Ru(1) is bonded to three equivalent O(2) and three 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 three inequivalent O sites. In the first O site, O(1) is bonded in a linear geometry to two equivalent Ba(3) atoms. In the second 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 third 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 face and corner-sharing OBa4Ru2 octahedra. The corner-sharing octahedral tilt angles range from 8-60°. is represented by the Crystallographic Information File (CIF) [CIF]
