The crystal structure described by La4Ru6O19 crystallizes in the cubic I23 space group. La(1) is bonded in a 10-coordinate geometry to one O(2), three equivalent O(1), and six equivalent O(3) atoms. Ru(1) is bonded to two equivalent O(1) and four equivalent O(3) atoms to form a mixture of edge and corner-sharing RuO6 octahedra. The corner-sharing octahedral tilt angles are 53°. There are three inequivalent O sites. In the first O site, O(1) is bonded in a 4-coordinate geometry to two equivalent La(1) and two equivalent Ru(1) atoms. In the second O site, O(2) is bonded in a tetrahedral geometry to four equivalent La(1) atoms. In the third O site, O(3) is bonded in a 3-coordinate geometry to two equivalent La(1) and two equivalent Ru(1) atoms. is represented by the CIF card [CIF]
