    Description / Table of Contents: Zusammenfassung Glutarsäuredihydrazid (GDH) und Adipinsäuredihydrazid (ADH) bilden mit Co(II)-Chlorid und Ni(II)-Chlorid bzw.-Nitrat in ethanolischer Lösung Komplexe der generellen ZusammensetzungenMLCl2,ML 2Cl2 und [NiL(H2O)2] (NO3)2, mitM=Co(II), Ni(II) undL=GDH,ADH. Für 1∶1-Komplexe von Co(II) wird eine tetragonale Geometrie, für alle anderen Komplexe eine oktaedrische Geometrie vorgeschlagen. Die Basis dazu lieferten Messungen der molaren Leitfähigkeit, der magnetischen Suszeptibilität und der UV- bzw. IR-Spektren.
    Notes: Abstract Glutaric dihydrazide (GDH) and adipic dihydrazide (ADH) have been found to react with Co(II) chloride and Ni(II) chloride and nitrate in ethanolic solution to form complexes of the general empirical compositionsMLCl2,ML 2Cl2 and [NiL 2(H2O)2] (NO3)2 whereM=Co(II), Ni(II) andL=GDH,ADH. Tetrahedral geometry has been proposed for 1∶1 complexes of Co(II) and octahedral geometry for the remaining complexes based on measurements of molar conductance, magnetic susceptibility, electronic and ir spectra.

    Notes: Summary Thorium as well as zirconium are quantitatively precipitated by o-cresotic acid at pH 3.7 and above. The precipitate in both the cases can be ignited and weighed as oxide. In the case of thorium, the precipitate can also be weighed directly as ThC8H14O8 after drying at 105–110

    Notes: From solutions of Th(NO3)4 and K2X (X = malonate, succinate and adipate) taken in different molar ratios, the following compounds were isolated: \documentclass{article}\pagestyle{empty}\begin{document}$$ \begin{array}{l} {\rm Th}({\rm C}_3 {\rm H}_2 {\rm O}_4)_2 \cdot 2{\rm H}_2 {\rm O},{\rm K}_2 {\rm Th}({\rm C}_3 {\rm H}_2 {\rm O}_4)_3, \\ {\rm Th}({\rm C}_4 {\rm H}_4 {\rm O}_4)_2 {\rm \,\,and \,\,Th}({\rm C}_2 {\rm H}_8 {\rm O}_2). \\ \end{array} $$\end{document}Conductometric and heterometric titrations carried out in the systems Th(NO3)4—K2X—H2O besides confirming the existence of the above compounds indicate the presence of yet another specie (ThX)++ in all these systems. Attempts at isolation of this last specie kowever, failed because of the ease with which it was decomposed into ThX2. The system Th(NO3)4—K2C2O4—H2O has also been studied for the sake of the completeness of the investigation.

    Notes: A number of complex malonates of the general formulae R2[MII(C3H2O4)2] · x H2O [where R — K, Na, and Tl(I); M(II) — Zn, Cd, Hg and Be] have been prepared by treating the freshly precipitated heavy metal hydroxide with a solution of alkali or thallous hydrogen malonate and submitting the resulting solution to crystallisation. The general behaviour of these compounds has been studied.

    Description / Table of Contents: Durch Reaktion von Zirkoniumnitrat mit den K-Salzen der Oxalsäure, Malonsäure, Apfelsäure, Bernsteinsäure, Adipinsäure und Phthalsäure in wäßriger Lösung konnten durch Fällung oder fraktionierte Kristallisation eine Reihe von Verbindungen erhalten werden (Formeln siehe Summary).Die Ergebnisse der präparativen Versuche konnten durch elektrometrische Titrationen und Trübungstitrationen bestätigt werden. Diese Methoden liefern außerdem Hinweise für das Auftreten eines komplexen Ions [ZrO(ZrOX)]++ in diesem System.
    Notes: From aqueous solution of Zr(NO3)4 and K2X (X-oxalate, malonate, malate, succinate, adipate and phthalate) taken in different molar proportions, the following compounds were prepared either by precipitation or by fractional crystallization methods. ZrO · C2O4 · 2 H2O; ZrO · C3H2O4, ZrO · C4H4O5, ZrO · C4H4O4, ZrO · C6H8O4; K2[ZrO(C2O4)2], K2[ZrO(C3H2O4)2] and K2[ZrO(C4H4O5)2].Conductometric, hetrometric and electrometric titrations carried out on the systems: ZrOCl2—K2X—H2O and Zr(NO3)4—K2X—H2O confirm the findings from the preparative studies. The first two type of titrations indicate the formation of the complex ion [ZrO(ZrOX)]++ in the above systems.

    Description / Table of Contents: Darstellung und Eigenschaften von Additionsverbindungen des SnCl4 mit N, N-Dimethylformamid, Acetamid, Acetanilid und Benzamid werden mitgeteilt. Neben der Analyse zeigen auch Donator-Acceptor-Titrationen in Dichloräthan die allgemeine Formel SnCl4 · 2 Amid. Leitfähigkeitsmessungen in Nitromethan und Molekulargewichtsbestimmungen lassen auf das Vorliegen von monomeren Additionsverbindungen schließen. Aus den IR-Spektren geht an Hand einer Erniedrigung der (C—O)- und einer Erhöhung der (C—N)-Valenzschwingung eine Bindung der organischen Liganden an das Zinn über Sauerstoff hervor. Die relativen Basenstärken nehmen in der Reihe Dimethylformamid, Benzamid, Acetanilid, Acetamid ab.
    Notes: The molecular addition compounds of tin (iv) chloride with N, N-dimethyl formamide, acetamide, acetanilide, and benzamide have been prepared. They are of the type SnCl4 · 2 amide. This composition type has been confirmed by indicator titrations of stannic chloride against amides in dichloroethane. Conductivity measurements in nitromethane and molecular weight determinations show that they are true molecular addition compounds being monomeric.The infrared spectra of the adducts show that there are metal-to-oxygen bonds in all these compounds as is evidenced by a negative shift of the carbonyl stretching frequency and a positive shift of the C—N stretching frequency. The relative donor ability of the amides towards stannic chloride has been found to be: dimethyl formamide 〉 benzamide 〉 acetanilide 〉 acetamide.
