The material structure described by Na2O2 is Tungsten Carbide-like structured and crystallizes in the orthorhombic Pbcm space group. Na(1) is bonded to six equivalent O(1) atoms to form a mixture of distorted face, corner, and edge-sharing NaO6 octahedra. The corner-sharing octahedral tilt angles range from 31-52°. O(1) is bonded to six equivalent Na(1) atoms to form a mixture of distorted corner and edge-sharing ONa6 pentagonal pyramids. is represented by the CIF card [CIF]
