K2RuHCl5 crystallizes in the orthorhombic Pnma space group. K(1) is bonded in a 9-coordinate geometry to two equivalent Cl(1), two equivalent Cl(3), two equivalent Cl(4), and three equivalent Cl(2) atoms. Ru(1) is bonded in an octahedral geometry to one H(1), one Cl(1), one Cl(3), one Cl(4), and two equivalent Cl(2) atoms. H(1) is bonded in a single-bond geometry to one Ru(1) atom. There are four inequivalent Cl sites. In the first Cl site, Cl(4) is bonded to four equivalent K(1) and one Ru(1) atom to form a mixture of distorted face, corner, and edge-sharing ClK4Ru square pyramids. In the second Cl site, Cl(1) is bonded to four equivalent K(1) and one Ru(1) atom to form a mixture of face, corner, and edge-sharing ClK4Ru square pyramids. In the third Cl site, Cl(2) is bonded in a distorted single-bond geometry to three equivalent K(1) and one Ru(1) atom. In the fourth Cl site, Cl(3) is bonded in a 5-coordinate geometry to four equivalent K(1) and one Ru(1) atom.
