    Description / Table of Contents: Zusammenfassung Es wurden Hexamminmetallkomplexe von Nickel(II), Chrom(III) und Kobalt(III) mit verschiedenen Oxo- und Thio-aniogen der Übergangsmetalle dargestellt und röntgenographisch sowie IR-spektroskopisch untersucht. Von einigen Verbindungen wurden kristallographische Daten ermittelt. An Hand der IR-Spektren wurde der Einfluß der Kationen auf die inneren Schwingungen der Anionen untersucht sowie auch die Abhängigkeit der Schwingungen der Kationen von der Natur der Anionen. Besonders wurden die NH3-“rocking”-Schwingungen in dieser Hinsicht untersucht, da sie bei gleichem Zentralatom des Amminkomplexes stark von der Art des Anions abhängig und somit für eine bestimmte Verbindung sehr charakteristisch sind.
    Notes: Abstract The preparation, the vibrational spectra, and X-ray data of oxo and thiometallates of transition metal hexammines are reported. The vibrational spectra and especially the influence of the anions on the NH3-rocking vibration are discussed.

    Notes: Abstract The mean amplitudes of vibration of ICl2 −, IBr2 −, BrCl2 − and ClF2 − have been calculated, from known spectroscopic data, in the temperature range between O° and 1000°K. Also generalized mean-square amplitudes and values for theBastiansen—Morino shrinkage effect are reported. The results are briefly discussed.

    Description / Table of Contents: Summary The sodium, ammonium, and lead(II) salts of the novel vanadyl(IV) complex bis(benzylmalonato)aquaoxovanadium(IV) have been prepared for the first time. They were characterized by means of electronic, IR, Raman and ESR spectroscopy. The thermal behaviour of the salts was investigated using TG and DTA methods.

    Notes: Summary The synthesis of a new vanadyl(IV)/saccharin complex is reported. Its bonding characteristics differ considerably from all known divalent metal-saccharinates. In this complex a VO(OH)+ moiety is coordinated to a saccharin molecule through its carbonyl oxygen and to a saccharinate ion through its deprotonated nitrogen. Two water molecules complete the coordination sphere. X-ray powder diagrams, infrared- and electronic absorption-spectra were recorded and analyzed for the characterization of the compound and its coordination properties. Besides, the magnetic susceptibility and the thermal behaviour were also investigated.

    Description / Table of Contents: Zusammenfassung Das elektrochemische Verhalten einer Reihe zweiwertiger Metallsaccharinate der Stöchiometrie [M II(sac)2(H2O)4]·2H2O wurde inDMF mit Hilfe cyclischer Voltammetrie an Glaskohlenstoff-Elektroden untersucht. Die Oxidation bzw. Reduktion von Fe(II) und Cu(II) erfolgt durch einen Einelektronenprozeß und erwies sich als quasi-reversibel. Die zweite Elektronenübertragung wird im Falle des Kupfersaccharinats von einer Zersetzung des Komplexes begleitet, welche unter Ligandenverlust zur Abscheidung von Kupfer auf der Elektrode führt. Im Falle der Ni(II)-, Fe(II)- und Co(II)-Komplexe wurde eine Reduktion des Liganden bei sehr negativen Potentialen beobachtet. Dagegen wurden für Natriumsaccharinat keine Oxidations- oder Reduktionspeaks beobachtet; der unkomplexierte Ligand erwies sich im untersuchten Potentialbereich als inaktiv.
    Notes: Summary The electrochemical behaviour of a series of divalent metal saccharinates of stoichiometry [M II(sac)2(H2O)4]·2H2O was studied by cyclic voltammetry inDMF solutions using a glassy carbon electrode. The oxidation and the reduction of the metallic centers Fe(II) and Cu(II), respectively, is shown to occur in one electron-steps and to be quasireversible. The second electron transfer for the copper saccharinate is followed by decomposition of the complex associated with loss of the ligand and copper electrodeposition. Reduction of the ligand was observed for Ni(II), Fe(II), and Co(II) saccharinates at highly negative potential. On the contrary, oxidation or reduction peaks were not observed with sodium saccharinate. The uncoordinated ligand was inactive in the analyzed potential range.

    Description / Table of Contents: Zusammenfassung Sechs VO2+-Komplexe von 8-Hydroxyquinolin (Oxin) und einige seiner mono- und dihalogenierten Derivate wurden dargestellt. Der Komplex des 5-Chloroxins erwies sich als besonders instabil und oxidiert sehr schnell unter Bildung eines V(V)-Komplexes der Stöchiometrie VO(QCl)2OH, welcher auch in reiner Form dargestellt werden konnte. Die Infrarotspektren aller Komplexe wurden aufgenommen und werden eingehend diskutiert. Die Komplexe mit halogenierten Liganden erscheinen als polymere Spezies, welche über V=O...V=O-Brücken wechselwirken. Die bei Raumtemperatur gemessenen magnetischen Momente zeigen die totale Abwesenheit von Orbitalbeiträgen. Die Analyse der Elektronenspektren weist auf ein besonders kompliziertes Lösungsverhalten hin, welches Oxidationsphänomene, Ligandenabspaltung und Wechselwirkung mit den Lösungsmitteln einschließt.
    Notes: Summary Six VO2+ complexes of 8-hydroxyquinoline (oxine) and of some of its mono- and dihalogenated derivatives have been prepared. The complex of 5-chloro-oxine is very unstable and oxidizes rapidly, generating a V(V) complex of stoichiometry VO(QCl)2OH which could also be prepared in pure form. The infrared spectra of all complexes have been recorded and are discussed in detail. The complexes containing halogenated ligands appear as polymeric species, interacting through V=O...V=O bridges. The magnetic moments, investigated at room temperature, indicate completely quenched orbital contributions. The analysis of the electronic spectra reveals very complex solution behaviour including, oxidation phenomena, ligand loss, and interaction with the solvent.
