The material described by RbCr2BiO8 crystallizes in the orthorhombic Pnna space group. Rb(1) is bonded in a 10-coordinate geometry to two equivalent O(1), two equivalent O(2), two equivalent O(4), and four equivalent O(3) atoms. 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 8-coordinate geometry to two equivalent O(1), two equivalent O(2), two equivalent O(3), and two equivalent O(4) atoms. There are four inequivalent O sites. In the first O site, O(1) is bonded in a 2-coordinate geometry to one Rb(1), one Cr(1), and one Bi(1) atom. In the second O site, O(2) is bonded in a single-bond geometry to one Rb(1), one Cr(1), and one Bi(1) atom. In the third O site, O(3) is bonded in a single-bond geometry to two equivalent Rb(1), one Cr(1), and one Bi(1) atom. In the fourth O site, O(4) is bonded in a distorted single-bond geometry to one Rb(1), one Cr(1), and one Bi(1) atom. is represented by the CIF file [CIF]
