RbNd(WO4)2 crystallizes in the monoclinic C2/c space group. Rb(1) is bonded in a 10-coordinate geometry to two equivalent O(1), two equivalent O(2), two equivalent O(3), and four equivalent O(4) atoms. Nd(1) is bonded in a 8-coordinate geometry to two equivalent O(1), two equivalent O(2), and four equivalent O(3) atoms. W(1) is bonded to one O(2), one O(3), two equivalent O(1), and two equivalent O(4) atoms to form a mixture of distorted corner and edge-sharing WO6 octahedra. The corner-sharing octahedral tilt angles are 40°. There are four inequivalent O sites. In the first O site, O(1) is bonded to one Rb(1), one Nd(1), and two equivalent W(1) atoms to form a mixture of distorted corner and edge-sharing ORbNdW2 tetrahedra. In the second O site, O(2) is bonded in a 3-coordinate geometry to one Rb(1), one Nd(1), and one W(1) atom. In the third O site, O(3) is bonded in a 2-coordinate geometry to one Rb(1), two equivalent Nd(1), and one W(1) atom. In the fourth O site, O(4) is bonded in a 4-coordinate geometry to two equivalent Rb(1) and two equivalent W(1) atoms.
