CrBiO5 crystallizes in the monoclinic P2_1/c space group. Cr(1) is bonded in a tetrahedral geometry to one O(1), one O(2), one O(3), and one O(4) atom. Bi(1) is bonded in a 6-coordinate geometry to one O(1), one O(4), two equivalent O(3), and two equivalent O(5) atoms. There are five inequivalent O sites. In the first O site, O(1) is bonded in a distorted bent 150 degrees geometry to one Cr(1) and one Bi(1) atom. In the second O site, O(2) is bonded in a single-bond geometry to one Cr(1) atom. In the third O site, O(3) is bonded in a distorted trigonal planar geometry to one Cr(1) and two equivalent Bi(1) atoms. In the fourth O site, O(4) is bonded in a distorted single-bond geometry to one Cr(1) and one Bi(1) atom. In the fifth O site, O(5) is bonded in a bent 120 degrees geometry to two equivalent Bi(1) atoms.
