摘要
The reaction of Ag(CH3SO3) with PPh3 gave the compound [Ag(CH3SO3)(PPh3)(2)] (I) and the reaction of Ag(CH3SO3) with PPh3 and 1,2-bis(4-pyridyl)ethane (Dpe) affords the mixed complex [Ag(CH3SO3)(PPh3)(Dpe)] (II). The crystal structures of I and II were determined by X-ray diffraction (CIF file CCDC no. 1563357 (for I)). In I, the centrosymmetric binuclear complex [Ag(CH3SO3)-(PPh3)(2)](2) is formed. The Ag atom has a distorted tetrahedral coordination composed of two bidentate bridging O atoms of the sulfonate anion and two P atoms of two PPh3 ligands. The structure of II is based on the centrosymmetric binuclear molecule with two bridging Dpe ligands between two [Ag(CH3SO3)(PPh3)] complexes. The O atoms of the methanesulfonate ion are statistically disordered, which induces a considerable distortion of the silver polyhedron with C.N. 5. Both compounds tend to emit in the blue and green regions of the PL spectra.
