The designed synthesis and structural characterization of two metal cluster-centered metallosupramolecular architectures are reported. In complex (CF(3)SO(3))Ag(4)((t)BuC≡C)(Py8)(2) (1) and (CF(3)SO(3))Ag(4){C≡C-(m-C(6)H(4))-C≡C-(m-C(6)H(4))-C≡C-(m-C(6)H(4))-C≡C}Ag(4)(CF(3)SO(3))(Py8)(2)(4) (2), organic acetylide ligands are utilized to induce the formation of polynuclear silver aggregates, which are encapsulated into the central cavity of the neutral macrocyclic compound azacalix[8]pyridine (Py8). The tetrasilver cluster centered [2]- and [3]-pseudo-rotaxane structures are obtained and fully characterized by X-ray crystallography, ESI mass spectrometry, and (1)H NMR spectroscopy.
报道了两种基于金属簇为中心的金属超分子结构的设计合成和结构表征。在配合物 (CF(3)SO(3))Ag(4)((t)BuC≡C)(Py8)(2)（1）和 (CF(3)SO(3))Ag(4){C≡C-(m-C(6)H(4))-C≡C-(m-C(6)H(4))-C≡C-(m-C(6)H(4))-C≡C}Ag(4)(CF(3)SO(3))(Py8)(2)(4)（2）中，利用有机炔基配体诱导多核银聚集体的形成，这些聚集体被封装在中性大环化合物氮杂杯[8]吡啶（Py8）的中央腔中。通过 X 射线晶体学、ESI 质谱和（1）H NMR 光谱学，得到了以四银簇为中心的[2]-和[3]-拟轮烷结构，并对其进行了充分的表征。
