Quadruple C-H Bond Activations of Methane by Dinuclear Rhodium Carbide Cation [Rh₂C₃].

ABSTRACT: The structure of the [Rh₂C₃]⁺ ion and its reaction with CH₄ in the gas phase have been studied by infrared photodissociation spectroscopy and mass spectrometry in conjunction with quantum chemical calculations. The [Rh₂C₃]⁺ ion is characterized to have an unsymmetrical linear [Rh-C-C-C-Rh]⁺ structure existing in two nearly isoenergetic spin states. The [Rh₂C₃]⁺ ion reacts with CH₄ at room temperature to form [Rh₂C]⁺ + C₃H₄ and [Rh₂C₂H₂]⁺ + C₂H₂ as the major products. In addition to the [Rh₂C]⁺ ion, the [Rh₂ ¹³
