Coordination of a Hemilabile N,N,S Donor Ligand in the Redox System [CuL2](+/2+), L=2-Pyridyl-N-(2 '-alkylthiophenyl)methyleneimine

Original language description

The new copper(I) complexes [Cu(L-1)(2)](BF4), L-1 = 2-pyridyl-N-(2'-methylthiophenyl)methyleneimine, and [Cu(L-2)(2)](ClO4), L-2 = 2-pyridyl-N-(2'-benzylthiophenyl)methyleneimine, have been prepared and structurally characterized. In contrast to the known [Cu(L-1)(2)](ClO4)(2), which exhibits partial thioether S binding to effect five-coordinate Cu2+, the copper(I) compounds reported here contain four-coordinate metal ions with exclusively N-donor binding. Cyclic voltammetry reveals a fully reversibleoxidation of the Cu-I species, which suggests a small barrier for reorganization. The reduction at negative potentials is irreversible for compounds [Cu(L)(2)](X) and for the structurally characterized new compound [Cu(L-1)(PPh3)(2)](ClO4). UV/Vis spectroelectrochemistry shows the typical low-energy absorption bands of copper(I) (MLCT transition) and copper(II) (ligand-field transition) in the visible region.
