We report herein the synthesis of a new metal cluster-encapsulated supramolecular capsule, (C≡C)@Ag(5-6)@(Py6)(2)(3-4) (3, Py6 = azacalix[6]pyridine), by use of a bowl-shaped macrocyclic ligand Py6. The multinuclear silver carbide cluster aggregate in 3 is encapsulated by two Py6 ligands through both metal-ligand coordination and cation-π interactions, spotlighting a new synthetic strategy for supramolecular capsules.
我们在此报告了一种新型金属簇封装的超分子胶囊(C≡C)@Ag(5-6)@(Py6)(2)3-4(3，Py6=氮杂杯[6]吡啶)的合成，该胶囊是通过使用碗状大环配体 Py6 来实现的。3 中的多核银碳化物簇聚集体通过金属-配体配位和阳离子-π 相互作用被两个 Py6 配体包裹，这突显了超分子胶囊的一种新的合成策略。
