Na4P2NO14O2 crystallizes in the monoclinic C2/c space group. The structure consists of four hydrogen peroxide molecules inside a Na4P2NO14 framework. In the Na4P2NO14 framework, there are two inequivalent Na sites. In the first Na site, Na(1) is bonded in a 4-coordinate geometry to one O(1), one O(2), one O(6), and one O(7) atom. In the second Na site, Na(2) is bonded in a 7-coordinate geometry to one N(1), one O(7), one O(8), two equivalent O(1), and two equivalent O(3) atoms. P(1) is bonded to one N(1), one O(1), one O(2), and one O(3) atom to form corner-sharing PNO3 tetrahedra. N(1) is bonded in a 2-coordinate geometry to two equivalent Na(2) and two equivalent P(1) atoms. There are seven inequivalent O sites. In the first O site, O(2) is bonded in a bent 150 degrees geometry to one Na(1) and one P(1) atom. In the second O site, O(3) is bonded in a distorted single-bond geometry to two equivalent Na(2) and one P(1) atom. In the third O site, O(5) is bonded in a single-bond geometry to one O(7) atom. In the fourth O site, O(6) is bonded in an L-shaped geometry to one Na(1) and one O(8) atom. In the fifth O site, O(7) is bonded in a 3-coordinate geometry to one Na(1), one Na(2), and one O(5) atom. In the sixth O site, O(8) is bonded in a 2-coordinate geometry to one Na(2) and one O(6) atom. In the seventh O site, O(1) is bonded to one Na(1), two equivalent Na(2), and one P(1) atom to form distorted edge-sharing ONa3P tetrahedra.
