We present a new family of Ag(I) complexes bearing calixarene-based tetraethynide ligands, namely, [Ag₁₂(L1)₂·(CH₃CN)₄·(NO₃)₄]·2H₂O (1), [Ag₄L1·(AgCF₃CO₂)₄·(CH₃OH)] (2), [Ag₄L2·(AgCF₃CO₂)₄]·H₂O (3), and [Ag₄L3·(AgCF₃CO₂)₄]·0.75CH₃COCH₃ (4), which were obtained from the reaction of newly synthesized tetraethynyl functionalized resorcin[4]arenes with silver(I) salts. Complex 1 features a 4/m assembly comprising a Ag₁₂ cage sandwiched by two bowl-shaped resorcin[4]arene tetraethynides, while 2–4 exhibit similar silver(I) chain structures each stabilized by an alternate attachment of bowl-shaped resorcin[4]arene tetraethynide units. This work provides the successful example of the use of calixarene-based ligands for the construction of multinuclear silver(I)–ethynide supramolecular frameworks.
