The structure described by K2Cu(OCl2)2 crystallizes in the tetragonal P4_2/mnm space group. K(1) is bonded in a rectangular see-saw-like geometry to four equivalent Cl(1) atoms. Cu(1) is bonded in a linear geometry to two equivalent O(1) atoms. O(1) is bonded in a distorted single-bond geometry to one Cu(1) and two equivalent Cl(1) atoms. Cl(1) is bonded in a 3-coordinate geometry to two equivalent K(1) and one O(1) atom. is represented by the CIF file [CIF]
