    • Compound 1: A MeOH (10 mL) solution of pyrazinecarbonitrile (120 mg, 1.10 mmol) was added dropwise to the MeOH solution (10 mL) of AgCF3CO2 (757 mg, 3.43 mmol) at room temperature. The solution was allowed to stand for one week, and pale yellow crystals formed that were collected by filtration, washed with MeOH, and dried in air. Yield: 145 mg (37, FT-IR (KBr, cm-1, ν, 3284, 3085, 2952, 1703, 1685, 1650, 1209, 1087. Anal. Calc. for C8H7AgF3N3O3: C, 26.84; H, 1.97; N, 11.74. Found: C, 26.99; H, 1.62; N, 11.66.

    • Single crystals of 1 and 2 were mounted on a Bruker SMART APEX CCD-based diffractometer and a Bruker P4 diffractometer equipped with the SMART CCD system, respectively. X-ray data for 1 and 2 were collected at 173(2) K and using MoKα radiation (λ, 0.71073 Å, graphite monochromator, The raw data were processed to give structure factors using the Bruker SAINT program and corrected for Lorentz and polarization effects. No absorption corrections were applied. The crystal structures were solved by direct methods, and refined by full-matrix least-squares refinement using the SHELXL97 computer program. All non-hydrogen atoms were refined anisotropically. All hydrogen atoms were positioned geometrically and refined using a riding model.
