CsSm(MoO4)2 crystallizes in the orthorhombic Pccm space group. Cs(1) is bonded in a 8-coordinate geometry to four equivalent O(2) and four equivalent O(3) atoms. Sm(1) is bonded in a 8-coordinate geometry to four equivalent O(1) and four equivalent O(2) atoms. Mo(1) is bonded in a tetrahedral geometry to one O(1), one O(3), and two equivalent O(2) atoms. There are three inequivalent O sites. In the first O site, O(1) is bonded in a 3-coordinate geometry to two equivalent Sm(1) and one Mo(1) atom. In the second O site, O(2) is bonded in a 2-coordinate geometry to one Cs(1), one Sm(1), and one Mo(1) atom. In the third O site, O(3) is bonded in a distorted single-bond geometry to two equivalent Cs(1) and one Mo(1) atom.
