Abstract

1:1 AgX:tz2(CH2) (X = NO3, NO2, ClO4), 3:4 (X = O3SOF3 (=OTf), O2CCF3 (= tfa)), and 2:1 adducts (X = BrO3) have been synthesized and characterized in the solid state and in solution by analyses, spectral (IR, far-IR, 1H and 13C NMR, ESI MS) data, and conductivity measurements. The crystal structures of the 1:1 AgNO3:tz2(CH2) and AgNO2:tz2(CH2) adducts determined by X-ray studies show that tz2(CH2) coordinates to silver through the exodentate nitrogen atoms at the 4-positions of the triazole rings, yielding neutral polymers, while the ionic Ag(OTf):tz2(CH2) (3:4) adduct has a three-dimensional polymeric cation. The NMR and ESI MS data suggest that tz2(CH2) is only weakly coordinating, adducts between Ag(I) and CH3CN being more prevalent in acetonitrile solution.
