用单晶x射线衍射法测定了一系列含银(I)盐联吡啶配体的氮或偶氮发色团的固态结构。超分子结构主要是由吡啶基-银-吡啶基键形成的一维链，但这些链通过非共价分子间相互作用形成的包装是不可预测的。Ag)中心点中心导中心导离子相互作用是重要的,尤其是对硝酸盐和高氯酸盐物种,但这些可能是支持或取代了Ag)中心导中心点中心导Ag)、Ag)中心导中心导中心点溶剂,Ag)中心导中心导中心点吖嗪或Ag)中心导中心点中心导π联系人。除了N， N'-双吡啶-4-基亚甲基肼的AgNO3配合物外，配体的分子结构在络合物的形成过程中几乎没有变化，其中通常平面的氮配体采用扭曲的几何形状。
The solid-state structures of a series of azine or azo chromophore containing bipyridyl ligand complexes of Ag(I) salts have been determined by single-crystal X-ray diffraction. The supramolecular structures are dominated by one-dimensional chains formed through pyridyl - Ag - pyridyl bonding, but the packing of these chains through non-covalent intermolecular interactions is unpredictable. Ag center dot center dot center dot anion interactions are shown to be important, especially for nitrate and perchlorate species, but these may be supported or replaced by Ag center dot center dot center dot Ag, Ag center dot center dot center dot solvent, Ag center dot center dot center dot azine or Ag center dot center dot center dot pi contacts. The molecular structures of the ligands show little alteration on complex formation, except for the AgNO3 complex of N, N'-bis-pyridin-4-ylmethylenehydrazine where the normally planar azine ligand adopts a twisted geometry.
