Materials Data on CrBiO4 by Materials Project
CrBiO4 is Zircon structured and crystallizes in the tetragonal I4_1/amd space group. The structure is three-dimensional. Cr5+ is bonded in a tetrahedral geometry to four equivalent O2- atoms. All Cr–O bond lengths are 1.73 Å. Bi3+ is bonded in a 8-coordinate geometry to eight equivalent O2- atoms. There are four shorter (2.42 Å) and four longer (2.50 Å) Bi–O bond lengths. O2- is bonded in a distorted single-bond geometry to one Cr5+ and two equivalent Bi3+ atoms.
