  1. 1. Formation and Decomposition of Platinum–Thallium Bond, Kinetics and Mechanism. Structural Characterization of Some Metal Cyanides in the Solid State

    Författare :Péter Nagy; KTH; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; metal–metal bond; platinum; thallium; kinetics; mechanism; stopped flow; oxidative addition; cyano complexes; edta; redox reaction; metal cyanides; X–ray diffraction; Raman; NMR; mercury; palladium; nickel; one dimensional wire;

    Sammanfattning : The kinetic and mechanistic features of a new series ofplatinum-thallium cyano compounds containing a direct andunsupported by ligands metal-metal bond have been studied insolution, using standard mix–and–measurespectrophotometric technique and stopped–flow method.These reactions are interpreted as oxidative addition of the cspecies to the square planar Pt(CN)42-complex.

    Sammanfattning : Artificial systems involving water oxidation and solar cells are promising ways for the conversion of solar energy into fuels and electricity. These systems usually consist of a photosensitizer, an electron donor and / or an electron acceptor. LÄS MER

  4. 3. Compounds with Non-Buttressed Metal-Metal Bond between Platinum and Thallium. Model Systems for Photoinduced Two-Electron-Transfer

    Författare :Mikhail Maliarik; KTH; []
    Nyckelord :thallium; platinum; cyanide; metal-metal bond; non-buttressed; heterometallic; photoinduced; electron transfer; redox reaction; NMR; chemical shift; spin-spin coupling constant; Raman; EXAFS; X-ray diffraction; equilibrium; oxidation state; oxidative;

    Sammanfattning : A new family of oligonuclear cyano compounds incorporatingtransition (Pt) and main group (Tl) metals bound with anon-buttressed Pt-Tl bond was synthesised in aqueous solution.The metal-metal linkage is formed in the reaction betweenplatinum and thallium in their stable oxidation forms, Pt(II)and Tl(III), orvice versa: Pt(IV) and Tl(I).
