revealed an ability to form stable binuclear copper(I) π-complexes. A series of related Cu(I) halides π-complexes, [Cu2(L)2X2] (X = Cl, 1a; Br, 1b; I, 1c), [Cu2(L)2I2]2 (1c’), [Cu2(L)2(CuCl2)2] (2), [Cu2(L)2Cu2Br4] (3) was obtained by alternating-current electrochemical synthesis, starting from acetonitrile solutions of the ligand L and CuX2 (in the case of 1a, 1b, 2, 3) or I2 (1c, 1c’). This is the
