The anion effects on the formation and photoluminescence(PL) of a series of AgX (X- = NO2-, NO3-, ClO4-, and PF6-) compounds with naphthalene-2,3-diyl-diisonicotinate (L) were investigated. According to the single-crystal X-ray structures, the NO2-, NO3-, and ClO4- anions act as anionic ligands rather than as simple counteranions whereas the PF6- anion acts as a simple counteranion. Correspondingly, the dinitroargentate anionic species, Ag(NO2)(2)(-), was observed in the solid state. The PL intensity of the present compounds, moreover, was proportional to the Ag center dot center dot center dot X distance, namely the metallophilicity of the anions. The weak- or non-coordinating anions, ClO4- and PF6-, could be smoothly exchanged with the NO2- or NO3- anion, whereas the reverse exchanges did not occur. The compounds%26apos; physicochemical properties were characterized by means of infrared (IR) spectroscopy, thermogravimetric analysis (TGA)/differential scanning calorimetry (DSC), and PL.
