Density functional theory (DFT) calculations are employed to investigate the structural and electronic properties of MoS6- and MoS6 clusters. Generalized Koopmans’ theorem is applied to predict the vertical detachment energies and simulate the photoelectron spectra (PES). Intriguingly, the terminal S2- , polysulfide S22- and S32- ligands simultaneously emerge in the lowest-energy structure of MoS6 . Molecular orbital analyses are performed to analyze the chemical bonding in MoS6-/0 clusters and elucidate their structural and electronic properties.
