6-Aminocoumarin reacts with pyridine-2-carboxaldehyde and has synthesized N-[(2-pyridyl)methyliden]-6-coumarin (L). The ligand, L, reacts with [Cu(MeCN)(4)]ClO4/AgNO3 to synthesize Cu(I) and Ag(I) complexes of formulae, [Cu(L)(2)]ClO4 and [Ag(L)(2)]NO3, respectively. While similar reaction in the presence of PPh3 has isolated [Cu(L)(PPh3)(2)]ClO4 and [Ag(L)(PPh3)(2)]NO3. All these compounds are characterized by FTIR, UV-Vis and H-1 NMR spectroscopic data. In case of [Cu(L)(PPh3)(2)]ClO4 and [Ag(L)(PPh3)(2)]NO3, the structures have been confirmed by X-ray crystallography. The structure of the complexes are distorted tetrahedral in which L coordinates in a N,N' bidentate fashion and other two coordination sites are occupied by PPh3. The ligand and the complexes are fluorescent and the fluorescence quantum yields of [Cu(L)(PPh3)(2)]ClO4 and [Ag(L)(PPb3)(2)]NO3 are higher than [Cu(L)(2)]ClO4 and [Ag(L)(2)]NO3. Cu(I) complexes show Cu(II)/Cu(I) quasireversible redox couple while Ag(I) complexes exhibit deposition of Ag(0) on the electrode surface during cyclic voltammetric experiments. GAUSSIAN 03 computations of representative complexes have been used to determine the composition and energy of molecular levels. An attempt has been made to explain solution spectra and redox properties of the complexes.
