Abstract:
Two novel silver(I) complexes [Ag(XANTphos)]BF4 (1) and [Ag2Cl2(DPEphos)2]center dot 2CH(2)Cl(2) (2) (XANTphos=9,9-dimethyl-4,5-bis (diphenylphosphanyl)xanthene, DPEphos=bis(2-(diphenylphosphino)phenyl)ether) have been synthesized in mixed solvent CH3OH and CH2Cl2 and characterized by IR, single-crystal X-ray diffraction, H-1 NMR spectroscopy and fluorescence spectra. Complex 1 is of a mononuclear complex,which was generated by the reaction of AgBF4 and XANTphos with dmp (neocuproine) in 1:1:1 molar ratio. The central ion Ag(I) forms a ring by the chelating bisphosphine ligand (XANTphos). While complex 2 is of a binuclear complex, which was obtained by the reaction of AgCl with DPEphos in 1:1 molar ratio. In the asymmetric unit of complex 2, each DPEphos ligand chelates one silver(I) cation with a free dichloromethane. The luminescent spectra show that all the emissions of the complexes 1 and 2 are assigned to ligand centered pi-pi* transition. CCDC: 1555835, 1; 1508048, 2.
