The material described by K4Ru2OCl10 crystallizes in the tetragonal I4/mmm space group. There are two inequivalent K sites. In the first K site, K(1) is bonded in a body-centered cubic geometry to eight equivalent Cl(1) atoms. In the second K site, K(2) is bonded to four equivalent Cl(2) and eight equivalent Cl(1) atoms to form KCl12 cuboctahedra that share corners with four equivalent K(2)Cl12 cuboctahedra, faces with four equivalent K(2)Cl12 cuboctahedra, and faces with four equivalent Ru(1)Cl5O octahedra. Ru(1) is bonded to one O(1), one Cl(2), and four equivalent Cl(1) atoms to form RuCl5O octahedra that share  a cornercorner with one Ru(1)Cl5O octahedra and faces with four equivalent K(2)Cl12 cuboctahedra. The corner-sharing octahedra are not tilted. O(1) is bonded in a linear geometry to two equivalent Ru(1) atoms. There are two inequivalent Cl sites. In the first Cl site, Cl(1) is bonded to two equivalent K(1), two equivalent K(2), and one Ru(1) atom to form a mixture of distorted edge, corner, and face-sharing ClK4Ru square pyramids. In the second Cl site, Cl(2) is bonded in a single-bond geometry to four equivalent K(2) and one Ru(1) atom. is represented by the CIF file [CIF]
