Materials Data on K2H2IrCl5O by Materials Project

Abstract

K2IrH2OCl5 crystallizes in the orthorhombic Pnma space group. The structure is three-dimensional. K1+ is bonded in a 8-coordinate geometry to eight Cl1- atoms. There are a spread of K–Cl bond distances ranging from 3.26–3.44 Å. Ir3+ is bonded in an octahedral geometry to one O2- and five Cl1- atoms. The Ir–O bond length is 2.11 Å. There are a spread of Ir–Cl bond distances ranging from 2.34–2.38 Å. H1+ is bonded in a single-bond geometry to one O2- atom. The H–O bond length is 0.99 Å. O2- is bonded in a distorted water-like geometry to one Ir3+ and two equivalent H1+ atoms. There are four inequivalent Cl1- sites. In the first Cl1- site, Cl1- is bonded to four equivalent K1+ and one Ir3+ atom to form distorted corner-sharing ClK4Ir square pyramids. In the second Cl1- site, Cl1- is bonded in a 5-coordinate geometry to four equivalent K1+ and one Ir3+ atom. In the third Cl1- site, Cl1- is bonded in a 1-coordinate geometry to two equivalent K1+ and one Ir3+ atom. In the fourth Cl1- site, Cl1- is bonded in a 5-coordinate geometry to four equivalent K1+ and one Ir3+ atom.
