 Title    Über Galvinole und Galvinoxyle, II EPR-HFS-und elektronen-spektroskopische Untersuchung On Galvinols and Galvinoxyls, II EPR and Electronic Absorption Spectra of Oligo Galvinoxyl Radicals in Solution  
 Abstract    The synthesis of several so far unknown mono-and oligo-galvinols and galvinoxyls is described. The ESR hyperfine splitting measurements in liquid solution indicate that the spin exchange frequency is greater than the hyperfine splitting in the galvinoxyl biradicals (J^>a). The electronic absorption spectra of the galvinols and galvinoxyls are discussed taking into account the different prototropic and redox equilibria, respectively. Using magnetic susceptibility measurements the singlet-triplet and doublet-quartet splitting is studied.

 Title    Halogenokomplexe von Osmium(III) mit Pyridin, Pyrazin, Pyrimidin und einigen Methylhomologen Halogeno-Complexes of Osmium(III) with Pyridine, Pyrazine, Pyrimidine and Some Methyl-Homologes Mer-trihalogeno-tris(N-donor)osmium(III) Complexes  
 Abstract    The preparation of mer-[OsX3B3], X = C1, Br, I; B = pyridine, 3-resp. 4-picoline, pyrimidine, pyrazine, methylpyrazine, and the chromatographic isolation of four base-mixed stereoisomers mer-[OsX3(py)n(mepyz)3_ n ], n— 1, 2, as solid crystalline products is described. Mass spectra and ligand exchange reactions confirm the structure of these complexes. The UV and IR spectra are discussed.

 Title    Tetrahalogeno -acetylacetonato -osmate (IV) Tetrahalogeno-acetylacetonato-osmates(IV)  
 Abstract    The complexes K[OsX4acac], X = Cl, Br, I, are prepared by treatment of K^fOsXß] with acetylacetone. The new compounds are characterized by their IR resp. visible and UV spectra which are highly resolved when measured on transparent pellets of the tetra-ethylammonium salts with KBr at 10 K. The influence of the different halide ligands on the bonding of the acac-group is discussed.
