Materials Data on CaCrO4 by Materials Project
CaCrO4 is Zircon structured and crystallizes in the tetragonal I4_1/amd space group. The structure is three-dimensional. Ca2+ is bonded in a 8-coordinate geometry to eight equivalent O2- atoms. There are four shorter (2.42 Å) and four longer (2.52 Å) Ca–O bond lengths. Cr6+ is bonded in a tetrahedral geometry to four equivalent O2- atoms. All Cr–O bond lengths are 1.67 Å. O2- is bonded in a 1-coordinate geometry to two equivalent Ca2+ and one Cr6+ atom.
