摘要:
Two novel silver (I) complexes, [Ag-2(dppp)(2)(phen)(2)] (CF3SO3)(2) (1) and [Ag-2(dppm)(2)(dpq)(2)] (CF3SO3)(2)center dot 3CH(3)OH (2) (dppp =bis (diphenylphosphino)propane, dppm = bis (diphenylphosphino)methane, phen =1,10-phenanthroline, dpq=pyrazino [2,3-f ][1,10]phenanthroline), have been synthesized in mixed solvent CH3OH and CH2C12 and characterized by IR, single-crystal X-ray diffraction, H-1 NMR spectroscopy, fluorescence spectra and THz time domain spectroscopy (THz-TDS). Complex 1 is of a binuclear complex,which was generated by the reaction of AgCF3SO3 and dppp with phen in 1:1:1 molar ratio. In complex 1, the central Ag(I) ion forms a ring by the bridging bisphosphine ligand (dppp) and chelating N-donor ligand (phen). Like 1, 2 is of a binuclear complex, which was obtained by the reaction of AgCF3SO3 and dppm with dpq in 1:1:1 molar ratio. The luminescent spectra show that all these emissions are assigned to ligand centered pi-pi* transition. CCDC: 890658, 1; 1571774, 2.
