Abstract:
Binuclear transition-metal complexes containing bidentate bridging ligands, L-L, have been the focus of much investigation in the last few years. Particularly, many examples with two bridges of the diphosphine Ph2PCH2PPh2 (dppm), including a variety of metals, oxidation states, and stereochemistries, have been described. They are generally characterized by the presence of an eight-membered ring M(μ-L-L)2M , in different conformations. The stereochemistry of the complex, the presence of metal- metal bond interactions and the nature of the second ligand in the structure effect on the photophysical properties of the binuclear complex which is very important in various applications such as OLEDs and optical devices [1]. In this work we have synthesized a new binuclear Cu(I) and Ag(I) complexes by treatment of [Cu(MeCN)4].PF6 and [Ag(MeCN)4].BF4 with dppm as a bridging ligand and another NN bidentate ligand at room temperature in dichloromethane which gives [Cu2(dppm)2(NN)2].PF6 and [Ag2(dppm)2(NN)2].BF4 respectively. The complexes were characterized by 1H,13C-NMR in solvent phase and X-ray crystallography in the solid state. These complexes demonstrated interesting photophysical properties as shown in Fig .1.
