The compound described by KSm(WO4)2 crystallizes in the orthorhombic Pbcn space group. K(1) is bonded in a 6-coordinate geometry to two equivalent O(4) and four equivalent O(1) atoms. Sm(1) is bonded in a 8-coordinate geometry to two equivalent O(2), two equivalent O(4), and four equivalent O(3) atoms. W(1) is bonded in a tetrahedral geometry to one O(1), one O(2), one O(3), and one O(4) atom. There are four inequivalent O sites. In the first O site, O(3) is bonded in a 3-coordinate geometry to two equivalent Sm(1) and one W(1) atom. In the second O site, O(4) is bonded in a 2-coordinate geometry to one K(1), one Sm(1), and one W(1) atom. In the third O site, O(1) is bonded in a distorted trigonal planar geometry to two equivalent K(1) and one W(1) atom. In the fourth O site, O(2) is bonded in a bent 120 degrees geometry to one Sm(1) and one W(1) atom. is represented by the CIF card [CIF]
