A direct synthetic route, based on silver(I) assisted metal exchange reaction, to cationic bis-ligand complexes of copper(I) involving N-aryl-pyridine-2-aldimines (L, 1) has been studied. These complexes are obtained as their perchlorates, [Cu(L)2]ClO4 (2). They have been characterized with the help of spectroscopy and X-ray crystallography. The X-ray structure of [Cu(L2)2]ClO4, where L2 is N-tolyl-pyridine-2-aldimine is reported. There are two crystallographically independent molecules in the asymmetric unit. The ligand L2 coordinates in a bidentate manner providing a highly distorted tetrahedral geometry about copper. The complexes show highly resolved symmetrical 1H NMR spectra. Intense MLCT absorptions are observed in the visible range. In methanol the CuL2+2/CuL+2 couple has E1/2 ca, 0.35 V vs SCE at 298 K. The moderately high positive potential is brought about by the distortion in the geometry of CuL2+2. Copyright
