The material structure described by (AlSeO9)2O2 is Zincblende, Sphalerite structured and crystallizes in the monoclinic P2_1/c space group. The structure is zero-dimensional and consists of two hydrogen peroxide molecules and two AlSeO9 clusters. In each AlSeO9 cluster, Al(1) is bonded in a 5-coordinate geometry to one O(3), one O(5), one O(8), and two equivalent O(4) atoms. Se(1) is bonded in a tetrahedral geometry to one O(6), one O(7), one O(8), and one O(9) atom. There are nine inequivalent O sites. In the first O site, O(7) is bonded in a single-bond geometry to one Se(1) atom. In the second O site, O(8) is bonded in a linear geometry to one Al(1) and one Se(1) atom. In the third O site, O(9) is bonded in a single-bond geometry to one Se(1) atom. In the fourth O site, O(2) is bonded in a single-bond geometry to one O(5) atom. In the fifth O site, O(10) is bonded in a single-bond geometry to one O(3) atom. In the sixth O site, O(3) is bonded in a bent 120 degrees geometry to one Al(1) and one O(10) atom. In the seventh O site, O(4) is bonded in a water-like geometry to two equivalent Al(1) atoms. In the eighth O site, O(5) is bonded in a bent 120 degrees geometry to one Al(1) and one O(2) atom. In the ninth O site, O(6) is bonded in a single-bond geometry to one Se(1) atom. is represented by the CIF card [CIF]
