The material described by ZnO2 is Baddeleyite-like structured and crystallizes in the orthorhombic P2_12_12_1 space group. Zn(1) is bonded to three equivalent O(1) and four equivalent O(2) atoms to form a mixture of distorted corner and edge-sharing ZnO7 pentagonal bipyramids. There are two inequivalent O sites. In the first O site, O(2) is bonded to four equivalent Zn(1) atoms to form a mixture of corner and edge-sharing OZn4 tetrahedra. In the second O site, O(1) is bonded in a trigonal non-coplanar geometry to three equivalent Zn(1) atoms. is represented by the Crystallographic Information File (CIF) [CIF]
