The reaction of silver nitrate with a substituted terpyridine ligand was investigated. The reaction of silver nitrate with 2,2':6',2''-terpyridine-1,1"-dioxide (tpyO2) in a 1:1 molar ratio resulted in the formation of the silver(I) complex [Ag(tpyO2)(H2O)]NO3•H2O (1). Moreover, the reaction of silver nitrate with 1,1"-dioxide-2,2':6',2''-terpyridine in the presence of KSCN led to the formation of complex [Ag(tpyO2)(SCN)]•2H2O (2). The products were characterized using IR, elemental analysis, multinuclear NMR spectroscopy, UV-Vis, and fluorescence spectroscopy. Thermal stability analysis of the complexes 1 and 2 revealed that the complexes [Ag(tpyO2)(H2O)]NO3•H2O and [Ag(tpyO2)(SCN)]•2H2O are stable up to 150 °C and 80 °C, respectively. The luminescent properties of the filled-shell d10 systems are of particular interest and have been the subject of various studies. The photoluminescence spectra for complexes 1 and 2 were recorded in the presence and absence of the specific metal ions. The sensing properties of 1 and 2 towards different metal ions were investigated, indicating that 1 and 2 exhibited greater sensitivity towards the Cd2+ ion than towards the other metal ions.
