PAPedro Oscar AbateConsejo Nacional de Investigaciones Científicas y TécnicasJRJosé Francisco RizoCentro de Investigaciones Científicas Isla de la CartujaFFFrancisco José Fernández‐de‐CórdovaCentro de Investigaciones Científicas Isla de la Cartuja

Key Points

  • The study aims to synthesize and characterize rhenium(I) complexes with pyrazine and pyridine functionalized ligands.
  • Synthesis of four rhenium(I) tricarbonyl complexes
  • Characterization through single-crystal X-ray diffraction
  • Electrochemical and spectroelectrochemical measurements
  • Successful synthesis of complexes featuring two different NHCs
  • Determined molecular structures through X-ray diffraction
  • Electrochemical properties measured, indicating responsive behavior

Abstract

Four rhenium(I) tricarbonyl complexes featuring pyridine- or pyrazine-functionalized N-heterocyclic carbenes were synthesized and fully characterized, including the determination of their molecular structures by single-crystal X-ray diffraction. Electrochemical and spectroelectrochemical measurements...
