The structure described by K2RuO5 crystallizes in the orthorhombic P2_12_12_1 space group. There are two inequivalent K sites. In the first K site, K(1) is bonded in a 7-coordinate geometry to one O(3), one O(4), one O(5), two equivalent O(1), and two equivalent O(2) atoms. In the second K site, K(2) is bonded in a 8-coordinate geometry to one O(1), one O(2), two equivalent O(3), two equivalent O(4), and two equivalent O(5) atoms. Ru(1) is bonded in a trigonal bipyramidal geometry to one O(1), one O(2), one O(3), one O(4), and one O(5) atom. There are five inequivalent O sites. In the first O site, O(1) is bonded in a 4-coordinate geometry to one K(2), two equivalent K(1), and one Ru(1) atom. In the second O site, O(2) is bonded to one K(2), two equivalent K(1), and one Ru(1) atom to form distorted corner-sharing OK3Ru tetrahedra. In the third O site, O(3) is bonded in a 4-coordinate geometry to one K(1), two equivalent K(2), and one Ru(1) atom. In the fourth O site, O(4) is bonded in a distorted single-bond geometry to one K(1), two equivalent K(2), and one Ru(1) atom. In the fifth O site, O(5) is bonded in a distorted single-bond geometry to one K(1), two equivalent K(2), and one Ru(1) atom. is represented by the CIF file [CIF]
