The crystal structure described by Rb2MoSO4 crystallizes in the trigonal R-3m space group. There are two inequivalent Rb sites. In the first Rb site, Rb(1) is bonded in a 10-coordinate geometry to one O(2) and nine equivalent O(1) atoms. In the second Rb site, Rb(2) is bonded in a 10-coordinate geometry to four equivalent S(1), three equivalent O(1), and three equivalent O(2) atoms. Mo(1) is bonded in a distorted tetrahedral geometry to one S(1) and three equivalent O(1) atoms. S(1) is bonded in a 5-coordinate geometry to four equivalent Rb(2) and one Mo(1) atom. There are two inequivalent O sites. In the first O site, O(1) is bonded in a distorted single-bond geometry to one Rb(2), three equivalent Rb(1), and one Mo(1) atom. In the second O site, O(2) is bonded in a distorted single-bond geometry to one Rb(1) and three equivalent Rb(2) atoms. is represented by the CIF card [CIF]
