The material structure described by Rb2Cr2Cd(H2O5)2 crystallizes in the triclinic P-1 space group. There are two inequivalent Rb sites. In the first Rb site, Rb(1) is bonded in a 9-coordinate geometry to one O(1), one O(4), one O(5), one O(7), one O(9), two equivalent O(10), and two equivalent O(2) atoms. In the second Rb site, Rb(2) is bonded in a 7-coordinate geometry to one O(4), one O(5), one O(6), one O(7), one O(8), and two equivalent O(3) atoms. There are two inequivalent Cr sites. In the first Cr site, Cr(1) is bonded to one O(3), one O(5), one O(6), and one O(7) atom to form CrO4 tetrahedra that share corners with two equivalent Cd(1)O6 octahedra. The corner-sharing octahedral tilt angles range from 39-52°. In the second Cr site, Cr(2) is bonded to one O(10), one O(2), one O(4), and one O(9) atom to form CrO4 tetrahedra that share corners with two equivalent Cd(1)O6 octahedra. The corner-sharing octahedral tilt angles range from 44-47°. Cd(1) is bonded to one O(1), one O(10), one O(4), one O(5), one O(6), and one O(8) atom to form CdO6 octahedra that share corners with two equivalent Cr(1)O4 tetrahedra and corners with two equivalent Cr(2)O4 tetrahedra. There are four inequivalent H sites. In the first H site, H(1) is bonded in a single-bond geometry to one O(1) atom. In the second H site, H(2) is bonded in a single-bond geometry to one O(8) atom. In the third H site, H(3) is bonded in a single-bond geometry to one O(1) atom. In the fourth H site, H(4) is bonded in a single-bond geometry to one O(8) atom. There are ten inequivalent O sites. In the first O site, O(1) is bonded in a water-like geometry to one Rb(1), one Cd(1), one H(1), and one H(3) atom. In the second O site, O(2) is bonded in a distorted single-bond geometry to two equivalent Rb(1) and one Cr(2) atom. In the third O site, O(3) is bonded in a distorted single-bond geometry to two equivalent Rb(2) and one Cr(1) atom. In the fourth O site, O(4) is bonded in a 4-coordinate geometry to one Rb(1), one Rb(2), one Cr(2), and one Cd(1) atom. In the fifth O site, O(5) is bonded in a 4-coordinate geometry to one Rb(1), one Rb(2), one Cr(1), and one Cd(1) atom. In the sixth O site, O(6) is bonded in a 3-coordinate geometry to one Rb(2), one Cr(1), and one Cd(1) atom. In the seventh O site, O(7) is bonded in a single-bond geometry to one Rb(1), one Rb(2), and one Cr(1) atom. In the eighth O site, O(8) is bonded in a distorted water-like geometry to one Rb(2), one Cd(1), one H(2), and one H(4) atom. In the ninth O site, O(9) is bonded in a single-bond geometry to one Rb(1) and one Cr(2) atom. In the tenth O site, O(10) is bonded in a 2-coordinate geometry to two equivalent Rb(1), one Cr(2), and one Cd(1) atom. is represented by the Crystallographic Information File (CIF) [CIF]
