Materials Data on SrAuO2 by Materials Project
SrAuO2 crystallizes in the monoclinic C2/m space group. The structure is three-dimensional. Sr2+ is bonded to six O2- atoms to form a mixture of corner and edge-sharing SrO6 octahedra. The corner-sharing octahedra tilt angles range from 19–36°. There are four shorter (2.60 Å) and two longer (2.62 Å) Sr–O bond lengths. There are two inequivalent Au2+ sites. In the first Au2+ site, Au2+ is bonded in a distorted linear geometry to two equivalent O2- atoms. Both Au–O bond lengths are 2.05 Å. In the second Au2+ site, Au2+ is bonded in a square co-planar geometry to four O2- atoms. There are two shorter (2.06 Å) and two longer (2.07 Å) Au–O bond lengths. There are two inequivalent O2- sites. In the first O2- site, O2- is bonded in a 5-coordinate geometry to four equivalent Sr2+ and one Au2+ atom. In the second O2- site, O2- is bonded in a distorted see-saw-like geometry to two equivalent Sr2+ and two Au2+ atoms.
