The material described by RbHfC(OF2)2O2 crystallizes in the monoclinic P2_1/c space group. The structure consists of four hydrogen peroxide molecules inside a RbHfC(OF2)2 framework. In the RbHfC(OF2)2 framework, Rb(1) is bonded in a 6-coordinate geometry to one O(2), one O(3), one F(1), one F(3), and two equivalent F(2) atoms. Hf(1) is bonded to one O(2), one O(3), one F(1), one F(2), one F(3), and two equivalent F(4) atoms to form distorted edge-sharing HfO2F5 pentagonal bipyramids. C(1) is bonded in a distorted bent 120 degrees geometry to one O(2) and one O(3) atom. There are two inequivalent O sites. In the first O site, O(2) is bonded in a 3-coordinate geometry to one Rb(1), one Hf(1), and one C(1) atom. In the second O site, O(3) is bonded in a 3-coordinate geometry to one Rb(1), one Hf(1), and one C(1) atom. There are four inequivalent F sites. In the first F site, F(2) is bonded in a 2-coordinate geometry to two equivalent Rb(1) and one Hf(1) atom. In the second F site, F(3) is bonded in a distorted bent 150 degrees geometry to one Rb(1) and one Hf(1) atom. In the third F site, F(4) is bonded in a water-like geometry to two equivalent Hf(1) atoms. In the fourth F site, F(1) is bonded in a distorted bent 150 degrees geometry to one Rb(1) and one Hf(1) atom. is represented by the Crystallographic Information File (CIF) [CIF]
