© 2017 The Royal Society of Chemistry. We report a photoelectron spectroscopy and high-resolution photoelectron imaging study of a bimetallic Nb2Au6- cluster. Theoretical calculations, in conjunction with the experimental data, reveal that Nb2Au6-/0 possess high-symmetry D6h structures featuring a Nb-Nb axis coordinated equatorially by an Au6 ring. Chemical bonding analyses show that there are two π bonds and one σ bond in the Nb2 moiety in Nb2
