The material structure described by RbH2O2F crystallizes in the tetragonal P-42_1m space group. There are three inequivalent Rb sites. In the first Rb site, Rb(1) is bonded in a body-centered cubic geometry to four equivalent O(1) and four equivalent O(2) atoms. In the second Rb site, Rb(2) is bonded to two equivalent F(2) and four equivalent F(1) atoms to form distorted edge-sharing RbF6 octahedra. In the third Rb site, Rb(3) is bonded in a 8-coordinate geometry to two equivalent O(1), two equivalent O(2), two equivalent F(1), and two equivalent F(2) atoms. There are two inequivalent H sites. In the first H site, H(1) is bonded in a linear geometry to one O(2) and one F(1) atom. In the second H site, H(2) is bonded in a distorted linear geometry to one O(1) and one F(2) atom. There are two inequivalent O sites. In the first O site, O(1) is bonded in a single-bond geometry to one Rb(1), one Rb(3), and one H(2) atom. In the second O site, O(2) is bonded in a single-bond geometry to one Rb(1), one Rb(3), and one H(1) atom. There are two inequivalent F sites. In the first F site, F(1) is bonded in a 2-coordinate geometry to two equivalent Rb(2), two equivalent Rb(3), and two equivalent H(1) atoms. In the second F site, F(2) is bonded in a 2-coordinate geometry to one Rb(2), two equivalent Rb(3), and two equivalent H(2) atoms. is represented by the Crystallographic Information File (CIF) [CIF]
