lkylation of ethylenediamine with allyl bromide in the presence of NaHCO3 in benzene–ethanol and acetone–ethanol gave N,N,N',N'tetraallylethylenediamine L4 and N,N,N,N',N'pentaallylethylenediaminium bromide (L5(H+)Br2), respectively. The ac electrochemical synthesis at copper wire electrodesin solutions of copper(II) halide and an appropriate ligand yielded single crystals of Cu(I) complexes withethylenediaminium ([L0(H+)2]0.5CuCl2 (I) and [L0(H+)2]0.5CuBr1.67Cl0.33 (II)) and its Nallyl derivativesN,N,N',N'tetraallylethylenediaminium ([{L4(H+)2}0.5Cu2Cl3] (III)) and N,N,N,N',N'pentaallylethylenediaminium ([L5(H+)Cu4Br6] (IV)). The crystal structures of complexes I–IV were determined by Xray diffraction. The isostructural crystals of complexes I and II are triclinic, space group P, Z = 2. For I:a= 5.936(3), b = 6.387(3), c = 7.126(4) Å, α = 67.82(4)°, β = 72.98(4)°, γ = 67.55(4)°, V = 227.7(2) Å3. For IIa= 6.110(3), b = 6.657(3), c = 7.309(3) Å, α = 68.40(3)°, β = 72.38(3)°, γ = 67.23(3)°, V = 250.4(2) Å3. In structures I and II, the organic cations are between infinite anionic chains (Cu)n. The crystals of πcomplex IIIare triclinic, space group P, a = 6.851(4), b = 8.729(4), c = 9.960(4) Å, α = 98.25(3)°, β = 102.29(3)°,γ= 107.30(3)°, V = 541.8(5) Å3, Z = 2. In structure III, all the four allyl groups are πcoordinated by the metalatoms of four discrete anions Cu4C The crystals of πcomplex IV are monoclinic, space group C2/c,a= 15.228(5), b = 17.095(6), c = 20.182(6) Å, β = 92.43(4)°, V = 5249(3) Å3, Z = 8. Only two of five allyl groupsat the same N atom are coordinated by copper(I) atoms. Structure IV contains a complex inorganic fragmentof the formula (Cu4B)
