catena-Poly[[silver(I)-μ-dipyrazin-2-ylamine] perchlorate monohydrate]

In the title complex, {[Ag(C(8)H(7)N(5))]ClO(4)·H(2)O}(n), the multidentate dipyrazin-2-ylamine acts as a μ(2)-bridging link with an anti–syn configuration, assembling the Ag(I) ions into a zigzag chain structure. The Ag(I) ion is linearly coordinated by two dipyrazin-2-ylamine ligands through two pyrazine N atoms. (ClO(4) (−))⋯π(pyrazine) [O⋯centroid distances of 3.612 (3) and 3.664 (1) Å] and π–π inter­actions [centroid–centroid distance = 3.518 (2) Å] as well as O—H⋯O and N—H⋯O hydrogen-bonds assemble the chains into a three-dimensional supra­molecular aggregation.
