title: catena-Poly[[silver(I)-μ-dipyrazin-2-ylamine] perchlorate monohydrate].
abstract: 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 inter-actions [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 supra-molecular aggregation.
