Rb2Bi(PO4)(WO4) crystallizes in the orthorhombic Ibca space group. Rb(1) is bonded in a 8-coordinate geometry to one O(3), two equivalent O(1), two equivalent O(2), and three equivalent O(4) atoms. W(1) is bonded in a tetrahedral geometry to two equivalent O(2) and two equivalent O(4) atoms. Bi(1) is bonded in a 8-coordinate geometry to two equivalent O(1), two equivalent O(2), and four equivalent O(3) atoms. P(1) is bonded in a tetrahedral geometry to two equivalent O(1) and two equivalent O(3) atoms. There are four inequivalent O sites. In the first O site, O(4) is bonded in a 4-coordinate geometry to three equivalent Rb(1) and one W(1) atom. In the second O site, O(1) is bonded in a distorted single-bond geometry to two equivalent Rb(1), one Bi(1), and one P(1) atom. In the third O site, O(2) is bonded in a 4-coordinate geometry to two equivalent Rb(1), one W(1), and one Bi(1) atom. In the fourth O site, O(3) is bonded in a distorted single-bond geometry to one Rb(1), two equivalent Bi(1), and one P(1) atom.
