Ru4Pb4O13 crystallizes in the cubic F-43m space group. Ru(1) is bonded to three equivalent O(1) and three equivalent O(2) atoms to form RuO6 octahedra that share corners with six equivalent Ru(1)O6 octahedra and edges with six equivalent Pb(1)O7 hexagonal pyramids. The corner-sharing octahedral tilt angles range from 44-46°. Pb(1) is bonded to one O(3), three equivalent O(1), and three equivalent O(2) atoms to form distorted PbO7 hexagonal pyramids that share corners with three equivalent Pb(1)O7 hexagonal pyramids, edges with three equivalent Pb(1)O7 hexagonal pyramids, and edges with six equivalent Ru(1)O6 octahedra. There are three inequivalent O sites. In the first O site, O(1) is bonded in a 4-coordinate geometry to two equivalent Ru(1) and two equivalent Pb(1) atoms. In the second O site, O(2) is bonded in a 4-coordinate geometry to two equivalent Ru(1) and two equivalent Pb(1) atoms. In the third O site, O(3) is bonded in a tetrahedral geometry to four equivalent Pb(1) atoms.
