Negative ion photoelectron spectroscopy of nineteen electron organometallic complexes Martel, Arthur Andrew
Abstract
The photoelectron spectra of the organometallic complexes CpCo(CO)₂⁻, MeCpMn(CO)₃⁻ and Co₂(CO)₄(NO)₂⁻, where Cp is the cyclopentadienyl ligand (C₅H₅) and MeCp the singly methylated analogue (CH₃-C₅H₄), have been obtained using Negative Ion Photoelectron Spectroscopy (NTPES) techniques. The experiments on CpCo(CO)₂⁻ and MeCpMn(CO)₃⁻ were performed at two separate laser photon wavelengths, 355 and 532 run. The cobalt dimer complex was examined only at 355 nm. Minimum vertical detachment energies for the three complexes were found to be 0.9 ± 0.1, 0.5 ± 0.1 and 2.0 ± 0.2 eV, respectively. The bond dissociation energy, D((CO)₃MnCpCH₂⁻-H), of one of the methyl hydrogens in the MeCpMn(CO)₃⁻ anion was found to be 2.2 ± 0.9 eV.

The photoelectron spectra of the organometallic complexes CpCo(CO)₂⁻,
MeCpMn(CO)₃⁻ and Co₂(CO)₄(NO)₂⁻, where Cp is the cyclopentadienyl ligand (C₅H₅) and MeCp the singly methylated analogue (CH₃-C₅H₄), have been obtained using Negative Ion Photoelectron Spectroscopy (NTPES) techniques.
The experiments on CpCo(CO)₂⁻ and MeCpMn(CO)₃⁻ were performed at two
separate laser photon wavelengths, 355 and 532 run. The cobalt dimer complex was
examined only at 355 nm. Minimum vertical detachment energies for the three complexes
were found to be 0.9 ± 0.1, 0.5 ± 0.1 and 2.0 ± 0.2 eV, respectively. The bond
dissociation energy, D((CO)₃MnCpCH₂⁻-H), of one of the methyl hydrogens in the MeCpMn(CO)₃⁻ anion was found to be 2.2 ± 0.9 eV.
