摘要：

A chiral supramolecular assembly encapsulates the two cationic ruthenium sandwich complexes [CpRu(eta(6)-C6H6)]+ and [CpRu(p-cymene)](+). The host-guest complexes K-11[CpRU(eta(6)-C6H6) subset of Ga4L6] (2) and K-11[CpRu(p-cymene) subset of Ga4L6] (3) were characterized by one- and two-dimensional NMR techniques as well as by electrospray mass spectrometry. Encapsulation of the prochiral complex [CpRu(p-cymene)](+) by the chiral host renders enantiotopic protons diastereotopic as evidenced by H-1 NMR spectroscopy.
