The compound described by RbLu(WO4)2 crystallizes in the monoclinic C2/c space group. Rb(1) is bonded in a 12-coordinate geometry to two equivalent O(2), two equivalent O(3), four equivalent O(1), and four equivalent O(4) atoms. Lu(1) is bonded in a 6-coordinate geometry to two equivalent O(2), two equivalent O(3), and two equivalent O(4) atoms. W(1) is bonded to one O(2), one O(4), two equivalent O(1), and two equivalent O(3) atoms to form a mixture of distorted corner and edge-sharing WO6 octahedra. The corner-sharing octahedral tilt angles are 44°. There are four inequivalent O sites. In the first O site, O(1) is bonded to two equivalent Rb(1) and two equivalent W(1) atoms to form a mixture of distorted corner and edge-sharing ORb2W2 trigonal pyramids. In the second O site, O(2) is bonded in a 2-coordinate geometry to one Rb(1), one Lu(1), and one W(1) atom. In the third O site, O(3) is bonded in a 4-coordinate geometry to one Rb(1), one Lu(1), and two equivalent W(1) atoms. In the fourth O site, O(4) is bonded in a 2-coordinate geometry to two equivalent Rb(1), one Lu(1), and one W(1) atom. is represented by the CIF file [CIF]
