The structure described by Na2O2 crystallizes in the monoclinic C2/m space group. Na(1) is bonded in a 6-coordinate geometry to six equivalent O(1) atoms. O(1) is bonded in a distorted body-centered cubic geometry to six equivalent Na(1) atoms. is represented by the Crystallographic Information File (CIF) [CIF]
