Five mono-nuclear silver (I) complexes with 6,7-dicyanodipyridoquinoxaline ligand, namely {[Ag(DPEphos)(dicnq)]NO3}2·CH3OH (1), [Ag(DPEphos)(dicnq)]BF4·CH3OH (2), [Ag(XANTphos)(dicnq)]CF3SO3 (3), {[Ag(XANTphos)(dicnq)]NO3}2 (4), and [Ag(XANTphos)(dicnq)]ClO4·CH2Cl2 (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, 1H NMR, 31P NMR, fluorescence spectra, and terahertz time-domain spectra (THz-TDS). In the five complexes the AgI, which is coordinated by two kinds of chelating ligands, adopts four-coordinate modes to generate mono-nuclear structures. The C?H···pi 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···pi interactions. The emissions of these complexes are attributed to ligands-centered [pi?pi*] transition based on both of the P-donor and N-donor ligands.
