    Details
    ISSN: 1572-9699
    Keywords: Myxozyma neotropica ; Candidaceae ; yeasts ; taxonomy
    Source: Springer Online Journal Archives 1860-2000
    Topics: Biology
    Notes: Abstract Two strains of an undescribed, soil-born species of the genusMyxozyma were recovered. They differ from other accepted species of this genus in their carbon assimilation pattern, mol% G+C and low extent of DNA complementary. A description of the new species,Myxozyma neotropica, and a key to the species accepted in the genus are given.

    Zur Komplexbildung von N-(Thiocarbamoyl)benzamidinen (1985)

    Description / Table of Contents: Complex Formation of N-(Thiocarbamoyl) benzamidinesN-(Thiocarbamoyl)benzamidines 1 and N-(Thiocarbamoyl)-N′-phenyl-benzamidines 2 form in alcoholic solutions with Ni2+, Cu2+, Pd2+, Co3+, and Ag+ ions well crystallized chelates 1a —h and 2a—h, respectively, with N/S coordination.The X-ray photoelectron spectra evidence the NH group as ligator in the case of chelates of 1 and the increased donor capacity compared with the isosteric oxygen ligator atom bound to nickel. This is confirmed by d-1H-n.m.r. spectroscopy analyzing the value of ΔGc≠ for the rotational barrier for the Et2N group of 1a
    Notes: N-(Thiocarbamoyl)banzamidine 1 und N-(Thiocarbamoyl)-N′-phenyl-benzamidine 2 bilden mit Ni2+-, Pd2+-, Co3+- und Ag+-Ionen in alkoholischer Lösung kristalline Innerchelatkomplexe1a—h und 2a—h mit N/S-Koordination.Aus ESCA-Spektren wird im Falle der Chelate von 1 als Haftgruppe NH nachgewiesen und ihre höhere Donorfähigkeit im Vergleich mit dem isosterne Sauerstoffhaftatom gegenüber Nickel fest-gestellt. Dies wird durch d-1H-NMR-spektroskopisch bestimmte Werte von ΔGc≠ für die behinderte Rotation der Et2N-Gruppe an 1 a unterstützt.

    Description / Table of Contents: Heavy Metal Chelates of α-Cyano-β-amino-dithioacrylatesThe inner metal chelates of PdII, NiII, CoIII, and AgI with α-cyano-β-amino-dithioacrylates have been prepared. The coordination of the dithioester group and the amine nitrogen (S/N-coordination) has been proved by the chemical shift of the S2p and N1s electron binding energies in the ESCA spectra.
    Notes: Es wurden Innerchelatmetallkomplexe des PdII, NiII, CuII, CoIII und AgI mit α-Cyano-β-amino-dithioacrylsäureestern dargestellt. Die Koordination der Dithiocarbonester-gruppierung und des Aminstickstoffs (S/N-Koordination) wird durch die chemische Verschiebung der S2p- und N1s-Elektronenbindungsenergien in den ESCA-Spektren bewiesen.
