K2RhH2OCl5 crystallizes in the orthorhombic Pnma space group. K(1) is bonded in a 6-coordinate geometry to one Cl(3), one Cl(4), two equivalent Cl(1), and two equivalent Cl(2) atoms. Rh(1) is bonded in a distorted rectangular see-saw-like geometry to one O(1), one Cl(1), one Cl(2), and one Cl(3) atom. H(1) is bonded in a single-bond geometry to one Cl(4) atom. O(1) is bonded in a single-bond geometry to one Rh(1) atom. There are four inequivalent Cl sites. In the first Cl site, Cl(4) is bonded in a single-bond geometry to one K(1) and one H(1) atom. In the second Cl site, Cl(1) is bonded to four equivalent K(1) and one Rh(1) atom to form distorted corner-sharing ClK4Rh square pyramids. In the third Cl site, Cl(2) is bonded in a 5-coordinate geometry to four equivalent K(1) and one Rh(1) atom. In the fourth Cl site, Cl(3) is bonded in a single-bond geometry to two equivalent K(1) and one Rh(1) atom.
