title: catena-Poly[[cyclo-tetra-mu-chlorotetracopper(I)]-bis{mu-3-[(2-morpholino-4-oxo-4,5-dihydro-1,3-thiazol-5-ylidene)methylphenoxy]propene}-2kappaN,1'eta2;1eta2,2'kappaN].
abstract: Crystals of a new copper(I) complex of composition [Cu4Cl4(C17H18N2O3S)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 pi center indicates that the Cu-(C=C) interaction is moderately effective.
