The material described by RbSm(MoO4)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. Sm(1) is bonded in a 8-coordinate geometry to two equivalent O(3), two equivalent O(4), and four equivalent O(2) atoms. Mo(1) is bonded in a 6-coordinate geometry to one O(2), one O(4), two equivalent O(1), and two equivalent O(3) atoms. There are four inequivalent O sites. In the first O site, O(1) is bonded in a distorted single-bond geometry to two equivalent Rb(1) and two equivalent Mo(1) atoms. In the second O site, O(2) is bonded in a 4-coordinate geometry to one Rb(1), two equivalent Sm(1), and one Mo(1) atom. In the third O site, O(3) is bonded in a 3-coordinate geometry to one Rb(1), one Sm(1), and two equivalent Mo(1) atoms. In the fourth O site, O(4) is bonded in a 2-coordinate geometry to two equivalent Rb(1), one Sm(1), and one Mo(1) atom. is represented by the CIF file [CIF]
