The crystal structure described by Li2RuO3 is Caswellsilverite-like structured and crystallizes in the monoclinic C2/m space group. There are three inequivalent Li sites. In the first Li site, Li(1) is bonded to two equivalent O(1) and four equivalent O(2) atoms to form LiO6 octahedra that share corners with two equivalent Li(3)O6 octahedra, corners with four equivalent Ru(1)O6 octahedra, edges with two equivalent Li(3)O6 octahedra, edges with three equivalent Li(1)O6 octahedra, edges with three equivalent Li(2)O6 octahedra, and edges with four equivalent Ru(1)O6 octahedra. The corner-sharing octahedral tilt angles range from 2-5°. In the second Li site, Li(2) is bonded to two equivalent O(1) and four equivalent O(2) atoms to form LiO6 octahedra that share corners with two equivalent Li(3)O6 octahedra, corners with four equivalent Ru(1)O6 octahedra, edges with two equivalent Li(3)O6 octahedra, edges with four equivalent Ru(1)O6 octahedra, and edges with six equivalent Li(1)O6 octahedra. The corner-sharing octahedral tilt angles range from 3-4°. In the third Li site, Li(3) is bonded to two equivalent O(1) and four equivalent O(2) atoms to form LiO6 octahedra that share corners with two equivalent Li(2)O6 octahedra, corners with four equivalent Li(1)O6 octahedra, edges with two equivalent Li(2)O6 octahedra, edges with four equivalent Li(1)O6 octahedra, and edges with six equivalent Ru(1)O6 octahedra. The corner-sharing octahedral tilt angles range from 3-4°. Ru(1) is bonded to two equivalent O(1) and four equivalent O(2) atoms to form RuO6 octahedra that share corners with two equivalent Li(2)O6 octahedra, corners with four equivalent Li(1)O6 octahedra, edges with two equivalent Li(2)O6 octahedra, edges with three equivalent Li(3)O6 octahedra, edges with three equivalent Ru(1)O6 octahedra, and edges with four equivalent Li(1)O6 octahedra. The corner-sharing octahedral tilt angles range from 2-5°. There are two inequivalent O sites. In the first O site, O(1) is bonded to one Li(2), one Li(3), two equivalent Li(1), and two equivalent Ru(1) atoms to form a mixture of edge and corner-sharing OLi4Ru2 octahedra. The corner-sharing octahedral tilt angles range from 0-2°. In the second O site, O(2) is bonded to one Li(2), one Li(3), two equivalent Li(1), and two equivalent Ru(1) atoms to form a mixture of edge and corner-sharing OLi4Ru2 octahedra. The corner-sharing octahedral tilt angles range from 0-5°. is represented by the CIF file [CIF]
