Materials Data on CrO by Materials Project

CrO crystallizes in the triclinic P1 space group. The structure is three-dimensional. there are six inequivalent Cr2+ sites. In the first Cr2+ site, Cr2+ is bonded in a distorted rectangular see-saw-like geometry to four O2- atoms. There are a spread of Cr–O bond distances ranging from 2.05–2.10 Å. In the second Cr2+ site, Cr2+ is bonded in a square co-planar geometry to four O2- atoms. There are two shorter (2.08 Å) and two longer (2.09 Å) Cr–O bond lengths. In the third Cr2+ site, Cr2+ is bonded in a distorted rectangular see-saw-like geometry to four O2- atoms. There are a spread of Cr–O bond distances ranging from 2.05–2.10 Å. In the fourth Cr2+ site, Cr2+ is bonded in a square co-planar geometry to four O2- atoms. There are two shorter (2.08 Å) and two longer (2.09 Å) Cr–O bond lengths. In the fifth Cr2+ site, Cr2+ is bonded in a square co-planar geometry to four O2- atoms. There are a spread of Cr–O bond distances ranging from 2.05–2.10 Å. In the sixth Cr2+ site, Cr2+ is bonded in a square co-planar geometry to four O2- atoms. There are a spread of Cr–O bond distances ranging from 2.05–2.10 Å. There are six inequivalent O2- sites. In the first O2- site, O2- is bonded in a square co-planar geometry to four Cr2+ atoms. In the second O2- site, O2- is bonded to four Cr2+ atoms to form a mixture of distorted edge and corner-sharing OCr4 trigonal pyramids. In the third O2- site, O2- is bonded to four Cr2+ atoms to form a mixture of distorted edge and corner-sharing OCr4 trigonal pyramids. In the fourth O2- site, O2- is bonded in a distorted square co-planar geometry to four Cr2+ atoms. In the fifth O2- site, O2- is bonded to four Cr2+ atoms to form a mixture of distorted edge and corner-sharing OCr4 trigonal pyramids. In the sixth O2- site, O2- is bonded to four Cr2+ atoms to form a mixture of distorted edge and corner-sharing OCr4 trigonal pyramids.
