The compound described by K2Zn2O3 crystallizes in the monoclinic P2_1/c space group. K(1) is bonded in a 4-coordinate geometry to two equivalent O(1) and two equivalent O(2) atoms. Zn(1) is bonded to one O(1) and three equivalent O(2) atoms to form a mixture of edge and corner-sharing ZnO4 tetrahedra. There are two inequivalent O sites. In the first O site, O(1) is bonded to four equivalent K(1) and two equivalent Zn(1) atoms to form corner-sharing OK4Zn2 octahedra. The corner-sharing octahedral tilt angles are 65°. In the second O site, O(2) is bonded in a 3-coordinate geometry to two equivalent K(1) and three equivalent Zn(1) atoms. is represented by the Crystallographic Information File (CIF) [CIF]
