By alternating‐current electrochemical technique, starting from CuCl 2 · 2H 2 O and tetraallylsilane (TAS), crystals of the π complex [Cu 5 Cl 5 (CH 2 –CH=CH 2 ) 4 Si] ( I ) were obtained, FTIR characterized and structurally investigated. The structure of I is monoclinic, space group P 2 1 / n , a = 12.292(3), b = 12.083(3), c = 13.356(3) Å, β = 90.19(3)°, V = 1983.7(9) Å 3 [at 100(2) K], Z = 4; R 1 = 0.0379, wR 2 = 0.1040 for 3583 reflections. The TAS molecule behaves as a tetradentate cross‐bridged ligand linking four (Cu 5 Cl 5 ) ∞ fragments through the C=C bonds. The influence of the inorganic part and ligand symmetries combined with their conformational abilities on the overall crystal symmetry is discussed.
