Redox Properties of C U(I) Camphor Hydrazone Complexes

The electrochemical properties of the one-dimensional coordination polymers [{CuX} 2(YNC 10 H14 O)] n (X=Cl: Y=NMe 2 1a , Y=NHMe 1b , Y=NH 2 1c ; X=Br: Y=NH 2 2c ) and dimers [{Cu(YNC 10 H14 O)} 2(µ-X) 2] (X=Cl: Y=NMe 2 3a ; Y=NHMe 3b ; X=Br: Y=NMe 2 4a ; Y=NHMe 4b ) were studied by cyclic voltammetry (CV) and controlled potential electrolysis (CPE). All complexes display anodic and cathodic processes. The anodic processes involve the oxidation of the metal site (Cu(I) �Cu(II)), while the cathodic processes are based on the ligand. The substituent (Y) at the camphor hydrazones (YNC 10 H14 O) plays a relevant role in the electrochemical properties and reactivity of Cu(I) coordination polymers and Cu(I) dimmers, as corroborated by CPE.
