The crystal structure described by K2RuH2O5 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(2), one O(4), one O(5), two equivalent O(1), and two equivalent O(3) atoms. In the second K site, K(2) is bonded in a 3-coordinate geometry to one O(3), one O(4), and two equivalent O(1) 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 two inequivalent H sites. In the first H site, H(1) is bonded in a single-bond geometry to one O(2) atom. In the second H site, H(2) is bonded in a single-bond geometry to one O(5) atom. There are five inequivalent O sites. In the first O site, O(4) is bonded in a 1-coordinate geometry to one K(1), one K(2), and one Ru(1) atom. In the second O site, O(5) is bonded in a distorted single-bond geometry to one K(1), one Ru(1), and one H(2) atom. In the third O site, O(1) is bonded in a 5-coordinate geometry to two equivalent K(1), two equivalent K(2), and one Ru(1) atom. In the fourth O site, O(2) is bonded in a distorted single-bond geometry to one K(1), one Ru(1), and one H(1) atom. In the fifth O site, O(3) is bonded in a distorted single-bond geometry to one K(2), two equivalent K(1), and one Ru(1) atom. is represented by the Crystallographic Information File (CIF) [CIF]
