Crystals of a new copper(I) π complex of composition [Cu ₄Cl₄(C₁₇H₁₈N₂O ₃S)₂]_n have been obtained by alternating-current electrochemical synthesis. In the crystal structure, the Cu and Cl atoms form a chair-like Cu₄Cl₄ cyclic fragment. The organic ligand acts as a bridge, being connected via the C=C bond of the allyl group to a Cu atom from one inorganic cycle and via the N atom of the thiazole ring to a Cu atom of another copper-chloride fragment. The geometry of the π center indicates that the Cu-(C=C) interaction is moderately effective.
