摘要
We present a detailed structural discussion of [Au-8(PPh3)(8)](NO3)(2), crystallized as a CH2Cl2 solvate. Its structure is compared with closely related triphenylphosphine-stabilized gold clusters. Characterization by optical extinction spectroscopy, luminescence spectroscopy, voltammetry and DFT calculations was performed to determine the electronic HOMO-LUMO gap. Comparison of its characteristic energies with those of structurally related clusters revealed that the evolution of the HOMO-LUMO gap does not follow a simple scaling law but depends on specific structural features.
