Probing delocalisation across highly ethynylated mono and dinuclear Pt(II) tethers containing nitrogroups and organic models as redox active probes: X-ray crystal structure of trans-[Pt(CC–C6H4NO2)2(PPh3)2]

The electrochemical study on Pt(II) organometallic and organic ethynylated compounds bearing nitro substituents in the phenyl groups has been performed, demonstrating that the presence of severe chemical irreversibility accompanying the electron transfer, preclude an evaluation of the electronic communication between redox active centres. The X-ray structure of the complex trans-[Pt(CC–C6H4NO2)2(PPh3)2] is showed.

Pt(II) organometallic and organic ethynylated compounds bearing nitro groups were synthesized and their electrochemical behaviour were investigated by cyclic voltammetry, revealing a chemical irreversibility for all the selected molecules.Figure optionsDownload as PowerPoint slide
