Title: Materials Data on SrHfO3 by Materials Project

Abstract

SrHfO3 crystallizes in the tetragonal P4/mbm space group. The structure is three-dimensional. there are two inequivalent Sr2+ sites. In the first Sr2+ site, Sr2+ is bonded in a 8-coordinate geometry to eight O2- atoms. There are four shorter (2.64 Å) and four longer (2.89 Å) Sr–O bond lengths. In the second Sr2+ site, Sr2+ is bonded in a 12-coordinate geometry to eight O2- atoms. There are four shorter (2.64 Å) and four longer (2.89 Å) Sr–O bond lengths. Hf4+ is bonded to six O2- atoms to form corner-sharing HfO6 octahedra. The corner-sharing octahedra tilt angles range from 0–24°. All Hf–O bond lengths are 2.09 Å. There are two inequivalent O2- sites. In the first O2- site, O2- is bonded in a 4-coordinate geometry to two equivalent Sr2+ and two equivalent Hf4+ atoms. In the second O2- site, O2- is bonded in a distorted linear geometry to four Sr2+ and two equivalent Hf4+ atoms.
