In the binuclear title compound, Ag(2)(C(11)H(11)N(3))(2)(2), the complex cation is centrosymmetric, with the unique Ag(+) cation coordinated by two pyridine N atoms from two symmetry-related N-(pyridin-2-ylmeth-yl)pyridin-2-amine ligands in a geometry slightly distorted from linear [N-Ag-N 161.02 (7)°]. This set-up leads to the formation of a 14-membered cyclic dimer. The two pyridine rings coordinated to the Ag(+) cation are tilted by 80.19 (7)° with respect to each other. Inter-molecular N-H⋯O hydrogen-bonding inter-actions between the cyclic dimer and the anion exist. A two-dimensional network parallel to the ac plane is constructed by three weak Ag⋯(O,N) inter-actions as well as an F⋯F contact of 2.890 (4) Å.
在双核标题化合物Ag₂(C₁₁H₁₁N₃)₂₂中,络合阳离子是中心对称的,独特的Ag⁺阳离子由来自两个对称相关的N-(吡啶-2-基甲基)吡啶-2-胺配体的两个吡啶N原子配位,其几何构型略微偏离线性[N-Ag-N 161.02 (7)°]。这种结构导致形成一个14元环状二聚体。与Ag⁺阳离子配位的两个吡啶环彼此倾斜80.19 (7)°。环状二聚体与阴离子之间存在分子间N-H⋯O氢键相互作用。通过三个弱的Ag⋯(O,N)相互作用以及2.890 (4) Å的F⋯F接触构建了一个平行于ac平面的二维网络。
