Silver(I) coordination networks constructed with di-2-pyrazinylmethanediol

The new ligand di-2-pyrazinylmethanone (di-2-pyrazinyl ketone), (2-C4H3N2)2CO, has been synthesized, and two silver(I) coordination polymers of its hydrated gem-diol (2-C4H3N2)2C(OH)2, namely {Ag[(2-C4H3N2)2C(OH)2](CF3SO3)}∞ (1) and {Ag[(2-C4H3N2)2C(OH)2](CF3CO2)}∞ (2), have been characterized by X-ray crystallography.
