Abstract
- We present a detailed structural discussion of [Au<subscript>8</subscript>(PPh<subscript>3</subscript>)<subscript>8</subscript>](NO<subscript>3</subscript>)<subscript>2</subscript>, crystallized as a CH<subscript>2</subscript>Cl<subscript>2</subscript> 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.
