Materials Data on Rb2CrH2Cl5O by Materials Project
Rb2CrH2OCl5 crystallizes in the orthorhombic Pnma space group. The structure is three-dimensional. Rb1+ is bonded in a 10-coordinate geometry to ten Cl1- atoms. There are a spread of Rb–Cl bond distances ranging from 3.37–3.92 Å. Cr3+ is bonded in an octahedral geometry to one O2- and five Cl1- atoms. The Cr–O bond length is 2.08 Å. There are a spread of Cr–Cl bond distances ranging from 2.37–2.40 Å. H1+ is bonded in a single-bond geometry to one O2- atom. The H–O bond length is 0.98 Å. O2- is bonded in a distorted trigonal planar geometry to one Cr3+ and two equivalent H1+ atoms. There are four inequivalent Cl1- sites. In the first Cl1- site, Cl1- is bonded in a distorted single-bond geometry to four equivalent Rb1+ and one Cr3+ atom. In the second Cl1- site, Cl1- is bonded in a 1-coordinate geometry to four equivalent Rb1+ and one Cr3+ atom. In the third Cl1- site, Cl1- is bonded in a 1-coordinate geometry to four equivalent Rb1+ and one Cr3+ atom. In the fourth Cl1- site, Cl1- is bonded in a distorted single-bond geometry to four equivalent Rb1+ and one Cr3+ atom.
