• We present an investigation on the structures and chemical bonding of two Bi-doped boron clusters BiBn[sup.−] (n = 4, 5) using photoelectron spectroscopy and theoretical calculations. The electron affinities of BiB[sub.4] and BiB[sub.5] are measured to be 2.22(2) eV and 2.61(2) eV, respectively. Well-resolved photoelectron spectra are obtained and used to compare with theoretical calculations to verify the structures of BiB[sub.4] [sup.−] and BiB[sub.5] [sup.−] . Both clusters adopt planar structures with the Bi atom bonded to the periphery of the planar Bn moiety. Chemical bonding analyses reveal that the Bn moiety maintains σ and π double-aromaticity. The Bi atom is found to induce relatively small structural changes to the Bn moiety, very different from transition metal-doped boron clusters.
