To goldly go… : Exclusive Au 11 (PPh 3 ) 8 Br 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 Au 11 core electrons with the benzene π electrons of the phosphine ligands was revealed by NMR spectroscopy and optical absorption spectroscopic analyses.
