Six novel 1 : 2 complexes of silver(I) nitrate with 2,5-, 2,6- and 3,5-dihalopyridines (halo stands for chlorine
and bromine) were prepared by the reaction of an aqueous solution of AgNO3 and the corresponding
pyridine derivative in a water–alcohol solution. In spite of having analogous empirical formulae, they reveal
intriguing structural differences, except [Ag(NO3)(2,5-Cl2py)2]n (1) and [Ag(NO3)(2,5-Br2py)2]n (4), which are
isostructural. In contrast, [Ag(NO3)(3,5-Cl2py)2]2 (3) is dimeric, while its Br analogue [Ag(NO3)(3,5-Br2py)2]n
(6) is polymeric in nature, being the only complex with no halogen⋯halogen interactions. Lastly, both
[Ag(NO3)(2,6-Cl2py)2] (2) and [Ag(NO3)(2,6-Br2py)2] (5) consist of monomeric molecules, with dissimilar
interaction patterns among units linking chains into different 3D structures. In addition, all isolated
complexes were identified by elemental analysis and characterized in solution by multinuclear NMR
spectroscopy (1H, 13C, 15N) and IR and mass spectrometry. DFT calculations verified the predominant
tendency of the Ag+ ions to bind two pyridine nitrogen atoms and one nitrate ion in their complexes and
confirm that their supramolecular structure is a compromise between competing weak intramolecular
interactions and steric constrains.
