The material structure described by (CaN2O9)2O2 crystallizes in the monoclinic P2_1/c space group. The structure is zero-dimensional and consists of two hydrogen peroxide molecules and two CaN2O9 clusters. In each CaN2O9 cluster, Ca(1) is bonded in a 7-coordinate geometry to one O(1), one O(10), one O(2), one O(5), one O(8), and two equivalent O(4) atoms. There are two inequivalent N sites. In the first N site, N(1) is bonded in a trigonal planar geometry to one O(1), one O(2), and one O(3) atom. In the second N site, N(2) is bonded in a trigonal planar geometry to one O(4), one O(5), and one O(6) atom. There are nine inequivalent O sites. In the first O site, O(6) is bonded in a single-bond geometry to one N(2) atom. In the second O site, O(7) is bonded in a bent 120 degrees geometry to one O(10) and one O(8) atom. In the third O site, O(8) is bonded in an L-shaped geometry to one Ca(1) and one O(7) atom. In the fourth O site, O(1) is bonded in an L-shaped geometry to one Ca(1) and one N(1) atom. In the fifth O site, O(2) is bonded in an L-shaped geometry to one Ca(1) and one N(1) atom. In the sixth O site, O(10) is bonded in a water-like geometry to one Ca(1) and one O(7) atom. In the seventh O site, O(3) is bonded in a single-bond geometry to one N(1) atom. In the eighth O site, O(4) is bonded in a distorted bent 150 degrees geometry to two equivalent Ca(1) and one N(2) atom. In the ninth O site, O(5) is bonded in a water-like geometry to one Ca(1) and one N(2) atom. is represented by the Crystallographic Information File (CIF) [CIF]
