Kurzfassung:
Five mono‐nuclear silver (I) complexes with 6,7‐dicyanodipyridoquinoxaline ligand, namely {[Ag(DPEphos)(dicnq)]NO 3 } 2 · CH 3 OH ( 1 ), [Ag(DPEphos)(dicnq)]BF 4 · CH 3 OH ( 2 ), [Ag(XANTphos)(dicnq)]CF 3 SO 3 ( 3 ), {[Ag(XANTphos)(dicnq)]NO 3 } 2 ( 4 ), and [Ag(XANTphos)(dicnq)]ClO 4 · CH 2 Cl 2 ( 5 ) {DPEphos = bis[2‐(diphenylphosphanyl)phenyl]ether, dicnq = 6,7‐dicyanodipyridoquinoxaline, XANTphos = 9,9‐dimethyl‐4,5‐bis(diphenylphosphanyl)xanthene} were characterized by X‐ray diffraction, IR, 1 H NMR, 31 P NMR, fluorescence spectra, and terahertz time‐domain spectra (THz‐TDS). In the five complexes the Ag I , which is coordinated by two kinds of chelating ligands, adopts four‐coordinate modes to generate mono‐nuclear structures. The C–H ··· π interactions lead to formation of a 1D infinite chain for complexes 2 and 3 . The crystal packing of complexes 1 and 5 reveal that they form 3D supermolecular network by several pairs of C–H ··· π interactions. The emissions of these complexes are attributed to ligands‐centered [π–π*] transition based on both of the P‐donor and N‐donor ligands.
