Abstract:
Five mono‐nuclear silver(I) complexes with the ligand 2,9‐dimethyl‐1,10‐phenanthroline, namely [Ag(DPEphos)(dmp)] BF 4 ( 1 ), [Ag(DPEphos)(dmp)]CF 3 SO 3 ( 2 ), [Ag(DPEphos)(dmp)]ClO 4 ( 3 ), [Ag(DPEphos)(dmp)]NO 3 ( 4 ), and [Ag(dppb)(dmp)]NO 3 · CH 3 OH ( 5 ) {DPEphos = bis[2‐(diphenylphosphanyl)phenyl]ether, dppb = 1,2‐bis(diphenylphosphanyl)benzene, dmp = 2,9‐dimethyl‐1,10‐phenanthroline} were characterized by X‐ray diffraction, IR, 1 H NMR, 31 P NMR and fluorescence spectroscopy. Their terahertz (THz) time‐domain spectra were also studied. In these complexes the silver(I), which is coordinated by two kinds of chelating ligands, adopts four‐coordinate modes to generate mono‐nuclear structures. In complexes 1 , 3 – 5 , offset π ··· π weak interactions exist between the neighboring benzene rings. In the 31 P NMR spectra, there exist splitting signals (dd), which can be attributed to the coupling of the 107,109 Ag– 31 P. All the emission peaks of these complexes are attributed to ligand‐centered excited states.
