In this study, pyrazolyl-1H-pyridine derivatives were proposed as ligands of this type, including 2-(3-phenyl-1H-pyrazole-5-yl)pyridine (L<sup>1</sup>) and 2-methyl-6-(3-phenyl-1H-pyrazole-5-yl)pyridine (L<sup>2</sup>). It was found that a complexes of the composition [AgPzL₁]<sub>n</sub> (1 : 1 : 1), regardless of the stoichiometry of the reactants, form in solution. When the resulting compounds are crystallized from toluene, binuclear complexes with the composition [AgPz₂Ln]₂ per one solvent molecule are formed. The formation of these structures is attributed to the formation of hydrogen bonds between the NH groups of pyrazole-pyridine (L<sup>n</sup>) and the unshared electron pairs of the nitrogen atoms of the pyrazolate ligands. Shortened Ag…Ag contacts (3.143-3.197 Å) are observed in the complex, leading to additional stabilization of the structure. As a result, the compounds exhibit ligand-centered phosphorescence in the solid state at room temperature.</p></abstract><trans-abstract xml:lang="ru"><p>Циклический трехъядерный комплекс серебра(I) [AgPz]<sub>3</sub>, где Pz = 3,5-бис(трифторметил)пиразолат, служит универсальной платформой для взаимодействия с хелатирующими N^N-донорными ароматическими лигандами. В настоящей работе в качестве лиганда данного типа предложены производные пиразолил-1H-пиридина (L) 2-(3-фенил-1H-пиразол-5-ил)пиридин (L<sup>1</sup>) и 2-метил-6-(3-фенил-1H-пиразол-5-ил)пиридин (L<sup>2</sup>). Установлено, что в растворе, независимо от стехиометрии реагентов, образуется комплексное соединение состава [AgPzL]<sub>n</sub> (1 : 1 : 1). При кристаллизации полученных соединений из толуола образуются биядерные комплексы состава [AgPzL<sup>n</sup>]<sub>2</sub> на одну молекулу растворителя. Формирование полученных структур обусловлено образованием водородной связи между NH-группой пиразолилпиридинов и неподеленной парой электронов атома азота пиразолатного лиганда. В комплексе наблюдаются укороченные контакты Ag<sub>···</sub>Ag (3.143–3.197 Å), что приводит к дополнительной стабилизации структуры. Полученные соединения проявляют лиганд-центрированную фосфоресценцию в твердом состоянии при комнатной температуре.</p></trans-abstract><kwd-group xml:lang="en"><kwd>pyrazolate ligand</kwd><kwd>silver(I)</kwd><kwd>photoluminescence</kwd><kwd>complexes formation</kwd></kwd-group><kwd-group xml:lang="ru"><kwd>пиразолатный лиганд</kwd><kwd>серебро(I)</kwd><kwd>фотолюминесценция</kwd><kwd>комплексообразование</kwd></kwd-group><funding-group/></article-meta></front><body></body><back><ref-list><ref id="B1"><label>1.</label><mixed-citation>Mohamed A.A. // Coord.
