Tetraethylammonium Dicopper(I) Triiodide and (18-Crown-6)potassium Dicopper(I) Triiodide

Tetraethylammonium triiododicopper(I), (C₈H₂₀N)[Cu₂I₃], and (18-crown-6)potassium triiododicopper(I), [K(C₁₂H₂₄O₆)][Cu₂I₃], crystallize with a polymeric series of edge-sharing Cu₂I₂ rhombs having Cu atoms bridged in pairs by an additional I atom, i.e. catena-poly[[copper(I)-₂-iodo-copper(I)]-di-₃-iodo]. The pattern of projection of bridging ₂-I atoms with respect to the polymeric band is up, down, up, down.
