    Divinylphenylene-bridged diruthenium complexes bearing Ru(CO)Cl((PiPr3Pr)2 entities

  • Original language description

    The divinylphenylene-bridged diruthenium complexes (E, E)-[{((PPr3)-Pr-i)(2)(CO)ClRu}(2)(mu-HC = CHC6H4CH = CH-1,3)] (m-2) and (E, E)-[{((PPr3)-Pr-i)(2)(CO)ClRu}(2)(mu-HC = CHC6H4CH = CH-1,4)](p-2) have been prepared and compared to their PPh3-containinganalogues m-1 and p-1. The higher electron density at the metal atoms increases the contribution of the metal end groups to the bridge-dominated occupied frontier orbitals and stabilizes the various oxidized forms with respect to those of m-1 and p-1. This has been confirmed and quantified electrochemically, because the two reversible oxidation waves were observed at considerably lower potentials than for the PPh3 complexes. Owing to their greater stability, the one- and two-electronoxidized forms m-2(n+) and p-2(n+) of both complexes could be generated and spectroscopically characterized inside an optically transparent thin layer electrolysis cell.

    Dirutheniové komplexy s divinylphenylenovým můstkem obsahující Ru(CO)Cl(PiPr3)2 fagment

  • Czech description

    Byly připraveny dirutheniové komplexy s divinylphenylenovým můstkem (E, E)-[{((PPr3)-Pr-i)(2)(CO)ClRu}(2)(mu-HC = CHC6H4CH = CH-1,3)] (m-2) and (E, E)-[{((PPr3)-Pr-i)(2)(CO)ClRu}(2)(mu-HC = CHC6H4CH = CH-1,4)](p-2)a porovnány s analogy obsahujícími PPh3,m-1 a p-1. Rozdíly v elektronické interakci jsou ilustrovány na základě nábojového rozložení získaného ze spektrální analýzy. Elektronová struktura těchto komplexů byla získána na základě kvantově chemických DFT výpočtů. Přechody v elektronových spektrech neutrálních komplexů byly přiřazeny pomocí TD DFT výpočtů.
