In the title complex, Ag(NO(3))(C(5)H(5)NO), the Ag(I) atom is coordinated by two O atoms from two different 4-pyridone ligands and two O atoms from one nitrate anion, displaying a nearly planar coordination geometry. The O atoms of two 4-pyridone ligands bridge two symmetrically related AgNO(3) units, forming a dimer, with an Ag⋯Ag separation of 3.680 (2) Å. Neighbouring dimers are linked into an infinite chain through weak Ag⋯O inter-actions [2.765 (2) Å], Ag⋯Ag inter-actions [3.1511 (4) Å] and π-π stacking inter-actions [centroid-centroid distance = 3.623 (4) Å]. N-H⋯O and C-H⋯O hydrogen bonds assemble these chains into a three-dimensional network.
在标题配合物[Ag(NO₃)(C₅H₅NO)]ₙ中，Ag(I)原子由来自两个不同4-吡啶酮配体的两个O原子和来自一个硝酸根阴离子的两个O原子配位，呈现出近乎平面的配位几何构型。两个4-吡啶酮配体的O原子桥连两个对称相关的AgNO₃单元，形成一个二聚体，Ag⋯Ag间距为3.680(2) Å。相邻的二聚体通过弱的Ag⋯O相互作用[2.765(2) Å]、Ag⋯Ag相互作用[3.1511(4) Å]和π-π堆积相互作用[质心-质心距离 = 3.623(4) Å]连接成无限链。N-H⋯O和C-H⋯O氢键将这些链组装成三维网络。
