Rb2CrH2OCl5 crystallizes in the orthorhombic Pnma space group. Rb(1) is bonded in a 9-coordinate geometry to two equivalent Cl(1), two equivalent Cl(2), two equivalent Cl(3), and three equivalent Cl(4) atoms. Cr(1) is bonded in an octahedral geometry to one O(1), one Cl(1), one Cl(2), one Cl(3), and two equivalent Cl(4) atoms. H(1) is bonded in a single-bond geometry to one O(1) atom. O(1) is bonded in a distorted trigonal planar geometry to one Cr(1) and two equivalent H(1) atoms. There are four inequivalent Cl sites. In the first Cl site, Cl(4) is bonded in a distorted single-bond geometry to three equivalent Rb(1) and one Cr(1) atom. In the second Cl site, Cl(1) is bonded in a 5-coordinate geometry to four equivalent Rb(1) and one Cr(1) atom. In the third Cl site, Cl(2) is bonded to four equivalent Rb(1) and one Cr(1) atom to form a mixture of distorted face, corner, and edge-sharing ClRb4Cr square pyramids. In the fourth Cl site, Cl(3) is bonded to four equivalent Rb(1) and one Cr(1) atom to form a mixture of distorted face, corner, and edge-sharing ClRb4Cr square pyramids.
