Materials Data on Na2ZnO2 by Materials Project
Na2ZnO2 crystallizes in the monoclinic P2_1/c space group. The structure is three-dimensional. there are two inequivalent Na1+ sites. In the first Na1+ site, Na1+ is bonded to four equivalent O2- atoms to form NaO4 tetrahedra that share corners with four equivalent NaO4 tetrahedra, corners with four equivalent ZnO4 tetrahedra, and edges with four equivalent NaO4 tetrahedra. There are a spread of Na–O bond distances ranging from 2.37–2.48 Å. In the second Na1+ site, Na1+ is bonded in a 5-coordinate geometry to five O2- atoms. There are a spread of Na–O bond distances ranging from 2.32–2.74 Å. Zn2+ is bonded to four O2- atoms to form distorted ZnO4 tetrahedra that share corners with four equivalent NaO4 tetrahedra, corners with four equivalent ZnO4 tetrahedra, and an edgeedge with one ZnO4 tetrahedra. There are a spread of Zn–O bond distances ranging from 1.94–2.12 Å. There are two inequivalent O2- sites. In the first O2- site, O2- is bonded in a 7-coordinate geometry to six Na1+ and one Zn2+ atom. In the second O2- site, O2- is bonded in a 6-coordinate geometry to three equivalent Na1+ and three equivalent Zn2+ atoms.
