    Notes: Die Untersuchung verschiedener physikalischer Eigenschaften von wäßrigen Jodsäurelösungen wird im einzelnen beschrieben. Durch Anwendung der Mischungsgleichung zur Eliminierung des Lösungsmitteleinflusses werden Kurven über die Abhängigkeit der untersuchten physikalischen Eigenschaft von der Konzentration der Lösung erhalten, die bei 0,1 n und 0,04 n Knicke bzw. Unstetigkeiten aufweisen. Alle Kurven ergeben praktisch das gleiche Bild. Diese Unstetigkeiten werden in der Weise gedeutet, daß bei den genannten Konzentrationen eine Depolymerisation von (HJO3)3 unter Bildung einfacher Moleküle eintritt, wahrscheinlich der Übergang (HJO3)3 → (HJO3)2 → (HJO3). Eine Prüfung der Ramanspektren bestätigte diesen Befund.

    Notes: Potassium manganimalonate has been prepared for the first time in the pure state. It has been assigned the formulae K3[Mn(CH2(COO)2)3] · 3 H2O. The compound when dissolved in water hydrolyses producing hydrated maganese dioxide, while it gives a clear deep red solution when added to an aqueous solution containing potassium malonate and malonic acid. This solution slowly decomposes at room temperature and is unaffected by light. It thus significantly differs from the corresponding decomposition of potassium manganioxalate which is distinctly photo-chemical.

    Description / Table of Contents: Aus Nickel(II)-phthalimid und Ammoniak, aliphatischen Aminen sowie einigen Diaminen wurden Komplexverbindungen der allgemeinen Formel Ni(phthalimid)2 · (Amin)2 hergestellt. Aus Leitfähigkeits- und kryoskopischen Messungen an Lösungen in Nitrobenzol geht hervor, daß diese Verbindungen in Nitrobenzol Nichtelektrolyte sind, d. h. daß auch das Phthalimidion als starker Ligand an das Ni(II) gebunden ist.
    Notes: Co-ordination complexes between nickel(II) phthalimide and ammonia, some aliphatic amines and a few diamines have been prepared. The molecular formulae on the basis of percentages of constituent elements are Ni(phthalimide)2 · (amine)2. Conductivity measurements in nitrobenzene indicate the complexes to be nonelectrolytes and hence it is suggested that the phthalimide ions are also coordinated. Molecular weight measurements in the same solvent confirm this.

    Description / Table of Contents: Durch Reaktion von VCl4 mit primären aromatischen Mono- und Diaminen wurden Aminkomplexe des Vanadin(IV)-chlorids erhalten. Aus ihrer Zusammensetzung wird geschlossen, daß das Zentralatom des VCl4 durch Anlagerung von zwei Monoamin-Molekeln bzw. einer Diamin-Molekel die Koordinationszahl 6 erlangt.
    Notes: The amino derivatives of V(IV) chloride have been prepared by the action of vanadium tetrachloride on some aromatic primary mono- and diamines. The compounds formed were analysed, their general properties studied and probable structure assigned. Analytical results reveal that 2 moles of a primary monoamine and one mole of a diamine are attached to one mole of vanadium tetrachloride.

    Description / Table of Contents: Die colorimetrische Untersuchung (Methode nach JOB) der wäßrigen Lösungen von (in fester Form nicht isolierbaren) Thallium(III)-azido(chloro)-Komplexen zeigt, daß drei stabile Komplexe vorliegen: [Tl(N3)6]3-, [Tl(N3)4]3- und [Tl(N32Cl4)3-]. Sie sind hellgelb, bei pH = 4,0-4,4 stabil und nicht durch Äthylacetat, Äther, Benzol oder CCl4 extrahierbar.
    Notes: Azido complexes of Tl(III) have been investigated colorimetrically. The results show the presence of three stable species in solution having the structures [Tl(N3)6]3-, [Tl(N3)4Cl2]3- and [Tl(N3)2Cl4]3-. The complexes posses bright yellow colour in aqueous solution, are stable between a pH range 4.0-4.4 and are inextractable by organic solvents such as ethylacetate, ether, benzene, or carbon tetrachloride. Attempts to isolate these in the crystalline state resulted in their hydrolysis.

    Description / Table of Contents: Aus Triarylgermaniumbromid (Aryl = Phenyl, p-Tolyl) wurden nach der Silbersalzmethode einige neue Triarylgermaniumverbindungen  -  z. B. Carboxylate, Sulfat, Selenat  -  erhalten und das schon beschriebene Bis-triphenylgermanium-sulfid2 nun aus der freien Base und H2S hergestellt. Aus IR-Spektren wird auf die Strukturen geschlossen.
    Notes: Several new triarylgermanium derivatives viz. triphenylgermanium benzoate, salicylate, mandelate, sulphate, selenite, selenate, tri-p-tolylgermanium benzoate and sulphate have been prepared by the interaction of triarylgermanium bromide with corresponding silver salt in an inert solvent. Triphenylgermanium acetate1 and bis-triphenylgermanium sulphide2, already described in the literature, have also been obtained by methods other than those reported. The compounds have been characterised, and their structures are discussed on the basis of infrared spectra.

    Description / Table of Contents: Komplexe des 1,5-disubstituierten 2,4-dithiobiurets mit Kupfer(II)-chloridDie im „Abstract“ aufgeführten Dithiobiurete reagieren mit wasserfreiem CuCl2 in Äthanol zu goldgelben Komplexen der allgemeinen Formel [CuL2]Cl2 (L = Biuret-Ligand). Auf Grund ihrer IR-Spektren sowie von Leitfähigkeits- und magnetischen Messungen wird auf quadratisch-planare Koordination geschlossen. Die ungewöhnlichen magnetischen Momentwerte von 1,11-1,35 BM deuten Metall-Metall-Bindung an.
    Notes: 1,5-diphenyl, 1,5-di-p-tolyl, 1-phenyl 5-0-tolyl, 1-phenyl 5-p-tolyl and 1-methyl 5-p-tolyl 2,4-dithiobiurets react with anhydrous copper(II) chloride in alcohol to form golden yellow complexes of general formula [CuL2]· Cl2, where L is a molecule of the ligand. The structures of these complexes have been studied by infrared spectroscopy, conductance and magnetic susceptibility measurements. The unusual magnetic moment (1.11-1.34 B.M.) values of these complexes are indicative of the metal-metal bonding. The structure of these complexes are proposed to have square planer configurations.

The complexes have been characterized on the basis of conductance, magnetic and i.r. spectral studies. Co-ordination through sulphur atom and tetrahedral configuration have been proposed for these complexes.

    Description / Table of Contents: Durch Umsetzung von VCl4 mit sek. und tert. Aminen wurden weitere Amin: V = 2:1-Derivate des Vanadin(IV)-chlorides erhalten, deren mögliche Strukturen diskutiert werden.
    Notes: Amino-derivatives of vanadium(IV) are prepared by the action of vanadium(IV) chloride with some secondary and tertiary amines, their properties studied and probable structures discussed. Analytical results reveal that two molecules of the amine are attached to one mole of vanadium(IV) chloride.The study of the amino-derivatives of vanadium(IV) chloride has been continued using the same methods of investigation as reported in Part I1). These compounds are very similar to the compounds formed with primary amines given in the previous work.The present work deals with the study of the preparation and properties of the compounds of vanadium tetrachloride with secondary and tertiary amines in non-aqueous media.
