N2 - Silver nitrate reacts with pyridines leading to complexes of different stoichiometry. These compounds feature: i) polymorphism, ii) ligands loss and iii) supramolecular association. Dissolution of AgNO 3 in liquid pyridines (py-R) results in formation of [Ag(py-R) n ](NO 3 ) ( n = 2, 3) complexes of different nature. Six complexes with py-R = pyridine (py), 2-methylpyridine (2-Mepy), 3-methylpyridine (3-Mepy), 4-methylpyridine (4-Mepy), 3,5-dimethylpyridine (3,5-Me 2 py), and 3-bromopyridine (3-Brpy) have been prepared and characterized by single crystal X-ray diffraction (SCXRD). The diffraction experiments were performed for i) crystals directly isolated from the mother liquor and ii) crystals of bulk samples stored after air-drying. The collected data show polymorphism or pyridine loss from [Ag(py-R) 3 ](NO 3 ) during the storage of bulk samples. The energies of Ag–N bonding inside the ionic pairs have been estimated by quantum-chemical calculations.
