The crystals of [(CH2)6N4(C 3H5)] Cu2Cl3 (I), [(CH 2)6N4(C3H5)]Cu 2Cl3 (II), and [(CH2)6N 4(C3H5)]CuCl2 (III) complexes were electrochemically synthesized (ac) from CuCl2·2H2O and N-allylhexamethylenetetraminium chloride in ethanol solutions at pH 6, 4.5, and 3. Their structures were determined using X-ray diffraction analysis (DARCh diffractometer, MoKα radiation, θ/2θ scan mode). Complex I crystallizes in the monoclinic system: space group A2/a, a = 24.812(6) Å, b = 8.855(3) Å, c = 12.080(2) Å, γ = 89.21(3)°, and Z = 8. Complex II crystallizes in the triclinic system: space group P1̄ , a = 7.618(2) Å, b = 7.048(2) Å, c = 13.150(3) Å, α = 97.50(2)°, β = 92.70(2)°, γ = 100.74(2)°, and Z = 2. The crystals of complex III are orthorhombic: space group Pmn21, a = 7.478(2) Å, b = 8.827(2) Å, c = 9.662(3) Å, Z = 2. The organic cation in complex I acts as a tridentate π,σ,σ-ligand; that in complex II, as a bidentate π,σ-ligand. In complex III, the organic cation is involved in coordination with the copper(I) atom only through one nitrogen atom.
