Abstract

1:1 AgX:tz(2)(CH(2)) (X = NO(3), NO(2), ClO(4)), 3:4 (X = O(3)SCF(3) (=OTf), O(2)CCF(3) (= tfa)), and 2:1 adducts (X = BrO(3)) have been synthesized and characterized in the solid state and in solution by analyses, spectral (IR, far-IR, (1)H and (13)C NMR, ESI MS) data, and conductivity measurements. The crystal structures of the 1:1 AgNO(3):tz(2)(CH(2)) and AgNO(2):tz(2)(CH(2)) adducts determined by X-ray studies show that tz(2)(CH(2)) coordinates to silver through the exodentate nitrogen atoms at the 4-positions of the triazole rings, yielding neutral polymers, while the ionic Ag(OTf):tz(2)(CH(2)) (3:4) adduct has a three-dimensional polymeric cation. The NMR and ESI MS data suggest that tz(2)(CH(2)) is only weakly coordinating, adducts between Ag(I) and CH(3)CN being more prevalent in acetonitrile solution.
