K2Li2Cu(OI)2 crystallizes in the tetragonal I4/mmm space group. K(1) is bonded in a 4-coordinate geometry to four equivalent O(1) and four equivalent I(1) atoms. Li(1) is bonded to four equivalent I(1) atoms to form a mixture of distorted corner and edge-sharing LiI4 tetrahedra. Cu(1) is bonded in a square co-planar geometry to four equivalent O(1) atoms. O(1) is bonded to four equivalent K(1) and two equivalent Cu(1) atoms to form a mixture of face, corner, and edge-sharing OK4Cu2 octahedra. The corner-sharing octahedra are not tilted. I(1) is bonded in a 8-coordinate geometry to four equivalent K(1) and four equivalent Li(1) atoms.
