摘要：

To goldly go: Exclusive Au11(PPh3)8Br 3 (see illustration) formation was obtained by a novel two-phase method, although the molar ratio of Br-/Cl- was 1:4, as identified by ESI-MS. Interestingly, the interaction of Au11 core electrons with the benzene π electrons of the phosphine ligands was revealed by NMR spectroscopy and optical absorption spectroscopic analyses.
