Abstract

Li6Hf2O7 crystallizes in the monoclinic C2/c space group. The structure is three-dimensional. there are three inequivalent Li1+ sites. In the first Li1+ site, Li1+ is bonded to five O2- atoms to form LiO5 square pyramids that share corners with nine LiO5 square pyramids, edges with four equivalent HfO6 octahedra, and edges with four LiO5 square pyramids. There are a spread of Li–O bond distances ranging from 2.00–2.28 Å. In the second Li1+ site, Li1+ is bonded to five O2- atoms to form distorted LiO5 square pyramids that share corners with three equivalent HfO6 octahedra, corners with six LiO5 square pyramids, edges with three equivalent HfO6 octahedra, and edges with five LiO5 square pyramids. The corner-sharing octahedra tilt angles range from 0–16°. There are a spread of Li–O bond distances ranging from 1.96–2.38 Å. In the third Li1+ site, Li1+ is bonded to five O2- atoms to form LiO5 square pyramids that share corners with nine LiO5 square pyramids, edges with four equivalent HfO6 octahedra, and edges with four LiO5 square pyramids. There are a spread of Li–O bond distances ranging from 2.00–2.30 Å. Hf4+ is bonded to six O2- atoms to form HfO6 octahedra that share corners with three equivalentmore »« less
