Rb2Mo(SO)2 crystallizes in the monoclinic P2_1/c space group. There are two inequivalent Rb sites. In the first Rb site, Rb(1) is bonded in a 8-coordinate geometry to three equivalent S(1), three equivalent S(2), one O(1), and one O(2) atom. In the second Rb site, Rb(2) is bonded in a 8-coordinate geometry to two equivalent S(1), two equivalent S(2), two equivalent O(1), and two equivalent O(2) atoms. Mo(1) is bonded in a distorted tetrahedral geometry to one S(1), one S(2), one O(1), and one O(2) atom. There are two inequivalent S sites. In the first S site, S(1) is bonded to two equivalent Rb(2), three equivalent Rb(1), and one Mo(1) atom to form a mixture of distorted corner and edge-sharing SRb5Mo octahedra. The corner-sharing octahedral tilt angles range from 10-40°. In the second S site, S(2) is bonded in a 1-coordinate geometry to two equivalent Rb(2), three equivalent Rb(1), and one Mo(1) atom. There are two inequivalent O sites. In the first O site, O(1) is bonded in a 4-coordinate geometry to one Rb(1), two equivalent Rb(2), and one Mo(1) atom. In the second O site, O(2) is bonded in a 4-coordinate geometry to one Rb(1), two equivalent Rb(2), and one Mo(1) atom.
