The material described by Rb5Gd(MoO4)4 crystallizes in the monoclinic P2/m space group. There are three inequivalent Rb sites. In the first Rb site, Rb(1) is bonded in a 8-coordinate geometry to one O(1), one O(6), two equivalent O(3), two equivalent O(4), and two equivalent O(5) atoms. In the second Rb site, Rb(2) is bonded in a 10-coordinate geometry to one O(2), one O(5), two equivalent O(3), two equivalent O(6), and four equivalent O(4) atoms. In the third Rb site, Rb(3) is bonded in a 12-coordinate geometry to two equivalent O(2), two equivalent O(5), four equivalent O(1), and four equivalent O(4) atoms. Gd(1) is bonded to two equivalent O(6) and four equivalent O(3) atoms to form GdO6 octahedra that share corners with two equivalent Mo(2)O4 tetrahedra and corners with four equivalent Mo(1)O4 tetrahedra. There are two inequivalent Mo sites. In the first Mo site, Mo(1) is bonded to one O(2), one O(5), and two equivalent O(3) atoms to form MoO4 tetrahedra that share corners with two equivalent Gd(1)O6 octahedra. The corner-sharing octahedral tilt angles are 48°. In the second Mo site, Mo(2) is bonded to one O(1), one O(6), and two equivalent O(4) atoms to form MoO4 tetrahedra that share  a cornercorner with one Gd(1)O6 octahedra. The corner-sharing octahedral tilt angles are 47°. There are six inequivalent O sites. In the first O site, O(1) is bonded in a distorted linear geometry to one Rb(1), two equivalent Rb(3), and one Mo(2) atom. In the second O site, O(2) is bonded in a 2-coordinate geometry to one Rb(2), one Rb(3), and one Mo(1) atom. In the third O site, O(3) is bonded in a 2-coordinate geometry to one Rb(1), one Rb(2), one Gd(1), and one Mo(1) atom. In the fourth O site, O(4) is bonded in a 1-coordinate geometry to one Rb(1), one Rb(3), two equivalent Rb(2), and one Mo(2) atom. In the fifth O site, O(5) is bonded in a distorted single-bond geometry to one Rb(2), one Rb(3), two equivalent Rb(1), and one Mo(1) atom. In the sixth O site, O(6) is bonded in a 2-coordinate geometry to one Rb(1), two equivalent Rb(2), one Gd(1), and one Mo(2) atom. is represented by the CIF card [CIF]
