Abstract

Bis-(pyridinal)-ethylenediimine (L) affords [(Cu2L2)-L-I]X-2 (X = ClO4- and PF6-). The X-ray crystal structure of the ClO4- salt shows that the cation [Cu-2(I):L-2](2+) is a double-stranded helicate. The PF6- salt exhibits a single emission band (maxima, 540 nm) in solution at room temperature (quantum yield: 2 x 10(-5) in methanol, 1 x 10(-5) in CH2Cl2). (C) 2000 Elsevier Science S.A.
