    Nyckelord :thallium; platinum; cyanide; n-donor ligand; metal-metal bond multinuclear NMR; raman spectroscopy;

    Sammanfattning : 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.

    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Coordination; Solvation; X-ray diffraction; EXAFS; IR; Raman; Normal coordinate analysis; trivalent metal ions; dmso; triflate; hydration; Chemistry; Kemi;

    Sammanfattning : Crystallographic and spectroscopic studies have been performed of structures, coordination and chemical bonding for series of trivalent metal ions solvated by two oxygen-coordinating solvents, water and dimethyl sulfoxide (DMSO). The hydrated scandium(III) and lanthanoid(III) ions, La to Lu, are surrounded by tricapped trigonal prisms of aqua ligands in the isomorphous series of trifluoromethanesulfonates, [M(H2O)n](CF3SO3)3.
