Sr4Ru6ClO18 crystallizes in the cubic I23 space group. Sr(1) is bonded in a 10-coordinate geometry to three equivalent O(2), six equivalent O(1), and one Cl(1) atom. Ru(1) is bonded to two equivalent O(2) and four equivalent O(1) atoms to form a mixture of edge and corner-sharing RuO6 octahedra. The corner-sharing octahedral tilt angles are 56°. There are two inequivalent O sites. In the first O site, O(2) is bonded in a water-like geometry to two equivalent Sr(1) and two equivalent Ru(1) atoms. In the second O site, O(1) is bonded in a 4-coordinate geometry to two equivalent Sr(1) and two equivalent Ru(1) atoms. Cl(1) is bonded in a tetrahedral geometry to four equivalent Sr(1) atoms.
Sr4Ru6ClO18 crystallizes in the cubic I23 space group. Sr(1) is bonded in a 10-coordinate geometry to three equivalent O(2), six equivalent O(1), and one Cl(1) atom. All Sr(1)-O(2) bond lengths are 3.03 Å. There are three shorter (2.55 Å) and three longer (2.74 Å) Sr(1)-O(1) bond lengths. The Sr(1)-Cl(1) bond length is 3.03 Å. Ru(1) is bonded to two equivalent O(2) and four equivalent O(1) atoms to form a mixture of edge and corner-sharing RuO6 octahedra. The corner-sharing octahedral tilt angles are 56°. Both Ru(1)-O(2) bond lengths are 1.93 Å. There are two shorter (1.97 Å) and two longer (2.00 Å) Ru(1)-O(1) bond lengths. There are two inequivalent O sites. In the first O site, O(2) is bonded in a water-like geometry to two equivalent Sr(1) and two equivalent Ru(1) atoms. In the second O site, O(1) is bonded in a 4-coordinate geometry to two equivalent Sr(1) and two equivalent Ru(1) atoms. Cl(1) is bonded in a tetrahedral geometry to four equivalent Sr(1) atoms.
