A “bowtie-shaped” Au5 moiety (structure shown on the right, PPh3 ligands on the terminal Au centers have been omitted) is the characteristic structural feature of the title complex. This is formed in high yield by the reaction of [AuCl(PPh3)] with [tBuNHLi] (1:1 equiv) in toluene. The cation can be regarded as the next homologue of cations of the type [(AuPPh3)3NR]+ and is the largest structurally characterized imidogold(I) species to date.
