Abstract—A supramolecular ensemble [{Ag3(Bipy)3(CN)}2Re6Se8(CN)6] (I) is synthesized by the reaction of Cs2.75K1.25[Re6Se8(CN)4(OH)2]·H2O with K[Ag(CN)2] and 2,2'-bipyridine (Bipy) under the hydrothermal synthesis conditions. The crystal structure consists of polymer layers [{Ag3(Bipy)3(CN)}2Re6Se8(CN)6]. Inside the layer, each cluster core {Re6Se8}2+ is linked with six Ag atoms via the CN bridge. Argentophilic interactions Ag···Ag (2.9035(6)–2.9697(5) Å) complete layer formation. π–π-Stacking interactions are observed both inside the layers and between the polymer layers. The synthesized compound is characterized by XRD (CIF file CCDC no. 2170365), IR spectroscopy, and elemental analysis.
