摘要: Reaction of AgNO3, dppm (bis(diphenylphosphino)methane), and TCNQ in molar ratio 1 : produced an acceptor–donor silver compound {[Ag2(dppm)2 (µ-TCNQ)2](TCNQ)}, 1. In the structure, determined by X-ray crystallography, two atoms are triply-bridged ligands metal–metal bond to form a dimer; distance between Ag is 3.1753(8) A. Compound was studied IR UV/Vis/NIR spectroscopy, exhibiting intervalence transfer transition at λ = 1286 nm, also photoluminescent (λmax 537 654 nm) room temperature.
