title: catena-Poly[[[mu-pyrazine-kappa2N:N'-disilver(I)]-di-mu-pyrazine-kappa4N:N'] bis(trifluoromethanesulfonate) dihydrate].
abstract: The title compound, {[Ag(2)(C(4)H(4)N(2))(3)](CF(3)SO(3))(2).2H(2)O}(n), is a polymeric pyrazine-silver(I) complex. Each Ag(I) ion is three-coordinated by N atoms of three different pyrazine ligands, forming a T-shaped coordination configuration. In the crystal structure, uncoordinated water molecules are linked to trifluoromethanesulfonate anions through intermolecular O-H...O hydrogen bonds. There are weaker Ag...O interactions involving the water and sulfonate O atoms.
