Summary:The structural and bonding properties of the Pt C (n = 1-3) complexes have been investigated by mass-selected photoelectron velocity-map imaging spectroscopy with quantum chemical calculations. The adiabatic detachment energies and vertical detachment energies of Pt C have been obtained from the measured photoelectron imaging spectra. Theoretical results indicate that the lowest-energy isomers of Pt C (n = 1-3) possess linear chain-shaped configurations. The binding motif in the most stable isomer of Pt C has a linear cumulenic structure with a Pt=C=C=Pt configuration, and the structural characteristic persists up to all the lowest-energy isomers of the Pt C and Pt C anions. The chemical bonding analyses indicate that the Pt C (n = 1-3) complexes have multicenter two-electron characteristics.
