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

    Author : Mikhail Maliarik; KTH; []
    Keywords : 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;

    Abstract : 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).

  4. 2. On Thallium (III) and binuclear platinum-thallium complexes with N-donor ligands in solution and in solid

    Author : Guibin Ma; KTH; []
    Keywords : thallium; platinum; cyanide; n-donor ligand; metal-metal bond multinuclear NMR; raman spectroscopy;

    Abstract : This thesis describes the synthesis, structure, equilibriaand other properties of novel thallium(III) monomeric andplatinum-bonded complexes with nitrogen donor ligandsethylenediamine, diethylenetriamine, triethylenetetramine,porphyrin, 2,2'-bipyridine and 1,10-phenanthroline in solutionand in solid.The existence of three complexes withthe general formula[Tl(en)n]3+(n = 1-3) and their overall stability constantshave been established in pyridine.
