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.
在标题配合物{[Ag(C₈H₇N₅)]ClO₄·H₂O}ₙ中，多齿的二吡嗪 - 2 - 基胺以反 - 顺构型作为μ₂ - 桥连配体，将Ag(I)离子组装成锯齿链结构。Ag(I)离子通过两个吡嗪N原子与两个二吡嗪 - 2 - 基胺配体呈线性配位。(ClO₄⁻)⋯π(吡嗪) [O⋯质心距离为3.612 (3) Å和3.664 (1) Å]以及π - π相互作用[质心 - 质心距离 = 3.518 (2) Å]，还有O - H⋯O和N - H⋯O氢键将这些链组装成三维超分子聚集体。
