    Description / Table of Contents: Eisen(II)- und Eisen(III)-chelate mit 1-Nitroso-2-naphthol und 5-Methoxy-2-nitrosophenol wurden spektroskopisch sowie mit der Dünnschichtchromatographie untersucht. Dabei zeigte sich, daß die Ladungsstufen Fe(II) und Fe(III) leicht ineinander übergehen und daß in äthanolischer Lösung die Fe(II)-Stufe, in benzolischer aber die Fe(III)-Stufe bevorzugt wird.2-4-Dinitrosoresorcin reagiert sowohl mit Fe(II) als auch mit Fe(III) unter Bildung des stabilen Fe(II)-chelats.
    Notes: Thin layer chromatograms and electronic spectra of iron II and iron III chelates of 1-nitroso-2-naphthol and 5-methoxy-2-nitrosophenol showed that they are readely interconvertable and that ethanol favors the iron II state whereas benzene favours the iron III state. 2-4-Dinitrosoresorcinol reacts with both iron II and iron III sulphate giving a stable iron II chelate.

    Description / Table of Contents: Es wurden kristalline CoIII- und NiII-Chelate einiger substituierter o-Nitrosophenole (siehe Summary) isoliert. Das Elektronenspektrum der Nickelchelate ist sowohl lösungsmittel- als auch temperaturabhängig, das der Kobaltchelate dagegen nicht.
    Notes: The cobalt(III) chelates of 1-nitroso-2-naphthol, 5-methoxy-2-nitrosophenol, 4-chloro-2-nitrosophenol and 4-bromo-2-nitrosophenol and the Ni(II) chelates of 2,4-dinitrosoresorcinol, 1-nitroso-2-naphthol, 5-methoxy-2-nitrosophenol, 4-chloro-2-nitrosophenol were obtained in a crystalline form by the interaction of Co(II) and Ni(II) salts with the ligands or their sodium salts. The electronic spectra of nickel chelates were solvent and temperature dependent while those of cobalt were unaffected by them.
