Abstract The electronic (UV-visible) spectrum of the molecular cluster Au55(PPh3)12Cl6 shows features corresponding to the 520 nm plasma resonance and the shorter-wavelength interband transition of colloidal gold. These absorptions differ qualitatively from the simpler one-electron transitions of lower-nuclearity cluster molecules. Differential scanning calorimetry has been used to measure the enthalpy of decomposition of Au55(PPh3)12Cl6. The Au-Au bonding appears to be substantially stronger than in bulk gold.
