The material described by Na2Zn2O3 is Ilmenite-like structured and crystallizes in the tetragonal P4_32_12 space group. Na(1) is bonded in a 4-coordinate geometry to one O(1) and three equivalent O(2) atoms. Zn(1) is bonded to one O(1) and three equivalent O(2) atoms to form a mixture of distorted corner and edge-sharing ZnO4 tetrahedra. There are two inequivalent O sites. In the first O site, O(1) is bonded in a 4-coordinate geometry to two equivalent Na(1) and two equivalent Zn(1) atoms. In the second O site, O(2) is bonded to three equivalent Na(1) and three equivalent Zn(1) atoms to form distorted edge-sharing ONa3Zn3 octahedra. is represented by the Crystallographic Information File (CIF) [CIF]
