For investigating the regulatory effects of the 1,3,5-trithiane (3S) in the formation of silver-alkynyl clusters, two new tetra-nucleus silver-alkynyl clusters, namely, [(3S)₄Ag₄(PhC≡C)(OTf)₂]·OTf·CH₃OH (1, OTf = CF₃SO₃⁻), and [(3S)₂Ag₄(^tBuC≡C)(tfa)₃]_n (2, tfa = CF₃CO₂⁻), were synthesized and their unique structures were investigated by single-crystal X-ray diffraction, Fourier-transform infrared spectroscopy, and powder X-ray diffraction analysis. Cluster 1 was a discrete cationic tetra-nucleus cluster co-ligated by 3S and phenylacetylene. Cluster 2 was a 2D coordination polymer based on a structurally similar tetra-nucleus cluster linking by 3S. Both clusters show excellent thermal stability and bright solid-state photoluminescence properties at room temperature. This work opens the door to using the supramolecular ligand-thiocrown ether to synthesize Ag clusters of attractive properties.

为了研究 1,3,5-三噻烷 ( 3S ) 在银-炔基簇形成中的调节作用，两个新的四核银-炔基簇，即 [( 3S ) ₄ Ag ₄ (PhC≡C) (OTf) ₂ ]·OTf·CH ₃ OH ( 1 , OTf = CF ₃ SO ₃ ^- ), [( 3S ) ₂ Ag ₄ ( ^t BuC≡C)(tfa) ₃ ] _n ( 2 , tfa = CF ₃ CO ₂ ^-), 并通过单晶 X 射线衍射、傅里叶变换红外光谱和粉末 X 射线衍射分析研究了它们的独特结构。簇1是由3S和苯乙炔共连接的离散阳离子四核簇。簇2是基于结构相似的四核簇通过3S连接的 2D 配位聚合物。两个团簇在室温下都表现出优异的热稳定性和明亮的固态光致发光特性。这项工作为使用超分子配体硫冠醚合成具有吸引力的 Ag 簇打开了大门。
