Materials Data on K2H2RhCl5O by Materials Project
K2RhH2OCl5 crystallizes in the orthorhombic Pnma space group. The structure is three-dimensional. K1+ is bonded in a 6-coordinate geometry to six Cl1- atoms. There are a spread of K–Cl bond distances ranging from 3.18–3.71 Å. Rh3+ is bonded in a distorted rectangular see-saw-like geometry to one O2- and three Cl1- atoms. The Rh–O bond length is 1.76 Å. There are two shorter (2.44 Å) and one longer (2.45 Å) Rh–Cl bond lengths. H1+ is bonded in a single-bond geometry to one Cl1- atom. The H–Cl bond length is 1.29 Å. O2- is bonded in a single-bond geometry to one Rh3+ atom. There are four inequivalent Cl1- sites. In the first Cl1- site, Cl1- is bonded in a single-bond geometry to one K1+ and one H1+ atom. In the second Cl1- site, Cl1- is bonded in a 5-coordinate geometry to four equivalent K1+ and one Rh3+ atom. In the third Cl1- site, Cl1- is bonded in a 5-coordinate geometry to four equivalent K1+ and one Rh3+ atom. In the fourth Cl1- site, Cl1- is bonded in a distorted single-bond geometry to two equivalent K1+ and one Rh3+ atom.
