Copper(I) π-complex {[C4H8ONH(C3H5)]+}2[Cu2Cl4]2− (I) was obtained by ac electrochemical synthesis from N-allylmorpholine hydrochloride and copper(II) chloride in ethanol and structurally characterized. In structure I, copper and chlorine atoms form unique noncentrosymmetric Cu2Cl 4 2− fragments. Both crystallographically independent N-allylmorpholinium cations are involved in the π-interaction and are coordinated by the copper atom through the C=C bond of the allyl group. The trigonal pyramidal environment of the Cu(1) atom is composed of three chlorine atoms and the C=C bond, while the Cu(2) atom coordinates two chlorine atoms and the C=C bond forming a planar triangle. The extremely strong N-C⋯Cl hydrogen bond (H⋯Cl 2.2 Å) prevents the Cl(1) atom from acting as a bridge and favors the formation of fragments Cu2Cl 4 2− .
