Copper(I) iodide complexes of novel structure: [Cu4I6][Cu8I13]K7(12-crown-4)6, [Cu4I6]K2(15-crown-5)2, and [Cu3I4]K(dibenzo-24-crown-8)

Aqueuous solutions of copper(I) iodide, potassium iodide, and the crown ether from unexpectedly different and novel structure: [Cu4I6][Cu8I13]K7(12-crown-4)6 with two different clusters per asymmetric, unit and polymeric modifications, [Cu4I6]K2(15-crown-5)2, and [Cu3I4]K(dibenzo-24-crown-8) depending upon identity of the crown ether.
