  Spectroelectrochemical studies on some new ruthenium(II) complexes containing both cyanide and isocyanide ligands

  摘要：

  New ruthenium(II) complexes trans, trans, trans-[RuCl(2)(NCR)(2)(CNR')(2)] (R = Me or Ph, R' = Bu', xylyl or cyclohexyl (cy)) have been prepared by treating mer-[RuCl(3)(NCR)(3)] with the appropriate isocyanide ligand CNR' in EtOH/CH(2)Cl(2). These complexes have been shown to be oxidisable electrochemically in situ to the analogous ruthenium(III) species trans, trans, trans[RuCl(2)(NCR)(2)(CNR')(2)](+) in 0.5 mol dm(-3) [NBu(4)(n)][PF(6)]/CH(2)Cl(2) solution, the stereochemistry of the oxidised species being established by use of an infrared spectroelectrochemical (IRRAS) technique. The electronic absorption spectra of the ruthenium(III) species obtained by use of an OTTLE cell are also reported and discussed. (C) 2000 Elsevier Science S.A. All rights reserved.

  From [RuX₆] to [Ru(RCN)₆]: synthesis of mixed halide–nitrile complexes of ruthenium, and their spectroelectrochemical characterization in multiple oxidation states

  摘要：

  A complete series of benzonitrile- and acetonitrile-substituted ruthenium halide complexes [RuX6-n(RCN)n]z (n = 0-6), ranging stepwise from [RuX6]2- to [Ru(RCN)6]2+, has been prepared and characterized. Three series were established, having RCN/X = PhCN/Cl, PhCN/Br, and MeCN/Cl. The strategy of reductive substitution has been developed to prepare [RuX5(RCN)]2-, trans-[RuX4(RCN)2]-, mer-[RuX3(RCN)3] and trans-[RuX2(RCN)4] in turn from [RuX6]2- by systematic electrosynthetic routes, through detailed management of potential, temperature and RCN concentration. The monosubstituted pentahalogeno complexes are unstable and their preparation is only practicable via electrode-induced (Ru(IV) --> Ru(III)) halide displacement from [RuX6]2- at low temperature. At the divalent level, exhaustive substitution to form [RuX(RCN)5]+ and [Ru(RCN)6]2+ from [RuX2(RCN)4] required more forcing chemical conditions (Ag+ and CF3SO3H respectively). Voltammetric studies between -65 and 20-degrees-C confirm that the family of mixed halide-nitrile monomeric complexes is rich in redox chemistry, spanning oxidation states V to II. Under reversible conditions, the various metal-based electrode potentials for [RuX6-n(RCN)n]z are a linear function of the stoichiometry parameter, n, increasing by 0.45 Ru(V)-Ru(IV)) or 0.6 V (Ru(IV)-Ru(III) and Ru(III)-Ru(II)) per halide replace by nitrile. By use of spectroelectrogeneration techniques, the optical charge-transfer spectra for every available member of each family have been recorded in multiple oxidation levels, defining the states Ru(IV) for n = 0-2, Ru(III) for n = 0-5 and Ru(II) for n = 2-6. For the present complexes, there are unmistakable complementary progressions in the halide-to-metal (X --> Ru(III)) and metal-to-ligand (Ru(II) --> RCN) bands, in accord with the underlying trend in E1/2(Ru(III)-Ru(II)). These measurements present an unusual opportunity to document and analyse the characteristic trends in appearance and location of both ligand-to-metal (Ru(III)) and metal-to-ligand (Ru(II)) charge-transfer manifolds as a function of stoichiometry.
