Materials Data on K2ZnO2 by Materials Project
K2ZnO2 crystallizes in the orthorhombic Ibam space group. The structure is three-dimensional. K1+ is bonded in a 5-coordinate geometry to five equivalent O2- atoms. There are a spread of K–O bond distances ranging from 2.67–3.02 Å. Zn2+ is bonded to four equivalent O2- atoms to form distorted edge-sharing ZnO4 tetrahedra. All Zn–O bond lengths are 2.04 Å. O2- is bonded in a 7-coordinate geometry to five equivalent K1+ and two equivalent Zn2+ atoms.
