The crystal structure described by Na3U2O6F7(O2)2 crystallizes in the triclinic P-1 space group. The structure consists of two hydrogen peroxide molecules inside a Na3U2O6F7 framework. In the Na3U2O6F7 framework, there are two inequivalent Na sites. In the first Na site, Na(1) is bonded in a 4-coordinate geometry to two equivalent O(5), one F(2), and two equivalent F(3) atoms. In the second Na site, Na(2) is bonded in a distorted rectangular see-saw-like geometry to two equivalent F(2) and two equivalent F(4) atoms. U(1) is bonded to one O(1), one O(2), one F(1), one F(2), one F(3), and two equivalent F(4) atoms to form a mixture of distorted edge and corner-sharing UO2F5 pentagonal bipyramids. There are three inequivalent O sites. In the first O site, O(1) is bonded in a single-bond geometry to one U(1) atom. In the second O site, O(2) is bonded in a single-bond geometry to one U(1) atom. In the third O site, O(5) is bonded in a 3-coordinate geometry to two equivalent Na(1) and one O(5) atom. There are four inequivalent F sites. In the first F site, F(1) is bonded in a linear geometry to two equivalent U(1) atoms. In the second F site, F(2) is bonded in a trigonal planar geometry to one Na(1), one Na(2), and one U(1) atom. In the third F site, F(3) is bonded in a distorted trigonal planar geometry to two equivalent Na(1) and one U(1) atom. In the fourth F site, F(4) is bonded in a distorted trigonal planar geometry to one Na(2) and two equivalent U(1) atoms. is represented by the Crystallographic Information File (CIF) [CIF]
