The material structure described by RbHS2O7 crystallizes in the monoclinic P2_1/c space group. Rb(1) is bonded in a 9-coordinate geometry to one O(1), two equivalent O(2), two equivalent O(4), two equivalent O(5), and two equivalent O(7) atoms. H(1) is bonded in a linear geometry to one O(1) and one O(6) atom. There are two inequivalent S sites. In the first S site, S(1) is bonded to one O(1), one O(2), one O(3), and one O(7) atom to form corner-sharing SO4 tetrahedra. In the second S site, S(2) is bonded to one O(3), one O(4), one O(5), and one O(6) atom to form corner-sharing SO4 tetrahedra. There are seven inequivalent O sites. In the first O site, O(5) is bonded in a distorted single-bond geometry to two equivalent Rb(1) and one S(2) atom. In the second O site, O(6) is bonded in a distorted bent 120 degrees geometry to one H(1) and one S(2) atom. In the third O site, O(7) is bonded in a single-bond geometry to two equivalent Rb(1) and one S(1) atom. In the fourth O site, O(1) is bonded in a distorted bent 120 degrees geometry to one Rb(1), one H(1), and one S(1) atom. In the fifth O site, O(2) is bonded in a single-bond geometry to two equivalent Rb(1) and one S(1) atom. In the sixth O site, O(3) is bonded in a bent 120 degrees geometry to one S(1) and one S(2) atom. In the seventh O site, O(4) is bonded in a distorted single-bond geometry to two equivalent Rb(1) and one S(2) atom. is represented by the Crystallographic Information File (CIF) [CIF]
