Materials Data on ZnO by Materials Project

Abstract

ZnO is Molybdenum Carbide MAX Phase-like structured and crystallizes in the hexagonal P6_3/mmc space group. The structure is three-dimensional. there are three inequivalent Zn2+ sites. In the first Zn2+ site, Zn2+ is bonded to six O2- atoms to form a mixture of corner and edge-sharing ZnO6 octahedra. The corner-sharing octahedral tilt angles are 0°. There are three shorter (2.16 Å) and three longer (2.17 Å) Zn–O bond lengths. In the second Zn2+ site, Zn2+ is bonded to six O2- atoms to form a mixture of corner and edge-sharing ZnO6 octahedra. The corner-sharing octahedral tilt angles are 0°. All Zn–O bond lengths are 2.16 Å. In the third Zn2+ site, Zn2+ is bonded to six equivalent O2- atoms to form a mixture of distorted corner and edge-sharing ZnO6 pentagonal pyramids. The corner-sharing octahedral tilt angles are 2°. All Zn–O bond lengths are 2.21 Å. There are three inequivalent O2- sites. In the first O2- site, O2- is bonded to six equivalent Zn2+ atoms to form a mixture of corner and edge-sharing OZn6 octahedra. The corner-sharing octahedral tilt angles are 0°. In the second O2- site, O2- is bonded to six Zn2+ atoms to form a mixture of corner, edge, and face-sharing OZn6 octahedra. The corner-sharing octahedra tilt angles range from 0–47°. In the third O2- site, O2- is bonded to six Zn2+ atoms to form a mixture of corner and edge-sharing OZn6 octahedra. The corner-sharing octahedral tilt angles are 0°.
