Materials Data on SrCrO2 by Materials Project
SrCrO2 crystallizes in the tetragonal P4/mmm space group. The structure is three-dimensional. Sr2+ is bonded in a body-centered cubic geometry to eight equivalent O2- atoms. All Sr–O bond lengths are 2.69 Å. Cr2+ is bonded in a square co-planar geometry to four equivalent O2- atoms. All Cr–O bond lengths are 2.04 Å. O2- is bonded to four equivalent Sr2+ and two equivalent Cr2+ atoms to form a mixture of distorted face, edge, and corner-sharing OSr4Cr2 octahedra. The corner-sharing octahedra tilt angles range from 0–65°.
