LiK(WO3)4 crystallizes in the tetragonal P4/mmm space group. The structure consists of one 7439-93-2 atom inside a K(WO3)4 framework. In the K(WO3)4 framework, K(1) is bonded to four equivalent O(3) and eight equivalent O(1) atoms to form KO12 cuboctahedra that share corners with four equivalent K(1)O12 cuboctahedra and faces with eight equivalent W(1)O6 octahedra. W(1) is bonded to one O(2), one O(3), and four equivalent O(1) atoms to form WO6 octahedra that share corners with six equivalent W(1)O6 octahedra and faces with two equivalent K(1)O12 cuboctahedra. The corner-sharing octahedral tilt angles range from 0-2°. There are three inequivalent O sites. In the first O site, O(1) is bonded in a distorted linear geometry to one K(1) and two equivalent W(1) atoms. In the second O site, O(2) is bonded in a linear geometry to two equivalent W(1) atoms. In the third O site, O(3) is bonded in a square co-planar geometry to two equivalent K(1) and two equivalent W(1) atoms.
