    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).

    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Alkoxides; Europium; Lanthanoids; Electronic absorption spectroscopy; f-f spectroscopy; Coordination chemistry; Koordinationskemi; Inorganic Chemistry; Oorganisk kemi;

    Sammanfattning : Coordination compounds of europium and titanium with oxide, ethoxide (OCH2CH3), iso-propoxide (OCH(CH3)2) and tert-butoxide (OC(CH3)3) ligands have been studied. These belong to the general class of oxo-alkoxides, MxOy(OR)z, with alkoxide ligands (OR) containing an organic, aliphatic part R. LÄS MER

  5. 4. Iron, Manganese and Iridium Complexes From Models of RNR and Catalase to Water Oxidation

    Författare :Michele Bedin; Anders Dr. Thapper; Sascha Prof. Ott; Vadim G. Kessler; Uppsala universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Iron; manganese; MnCAT; RNR; biomimetic; Kemi; Chemistry;

    Sammanfattning : The focus of this thesis has been synthesise and study metal complexes that mimic the structure and function of the active site in two particular metalloenzymes, ribonucleotide reductase (RNR) and manganese catalase (MnCAT). These two metalloenzymes both have two transition metals ions in the cofactor: two manganese ions in MnCAT and either two iron, iron-manganese or two manganese ions in RNR. LÄS MER

  7. 5. Synthesis and characterisation of heterobimetallic erbium alkoxides

    Författare :Maria Wijk; Jean Galy; Stockholms universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Inorganic chemistry; Oorganisk kemi; oorganisk kemi; Inorganic Chemistry;

    Sammanfattning : This thesis describes the synthesis and characterisation of alkoxides in the Er-M systems, where M = Al, Ti and Zr. The compounds found have been characterised by IR, UV-Vis DSC and single-crystal X-ray diffraction techniques and by chemical behaviour. LÄS MER
