The material structure described by Na2O is Hydrophilite-like structured and crystallizes in the orthorhombic Pnnm space group. Na(1) is bonded in a trigonal planar geometry to three equivalent O(1) atoms. O(1) is bonded to six equivalent Na(1) atoms to form a mixture of corner and edge-sharing ONa6 octahedra. The corner-sharing octahedral tilt angles are 53°. is represented by the Crystallographic Information File (CIF) [CIF]
