    Description / Table of Contents: Darstellung und IR-Untersuchungen der Komplexe von Methylethyl-, Ethyl(n-Propyl)-und n-Propyl (n-Butyl)zinn-dichloriden mit einigen StickstoffdonatorenEs wurden die Komplexe von Methylethylzinn-dichlorid mit 3-, 4-Picolinen, Isoquinolin und Benzylamin, von Ethyl(n-propyl)zinn-dichlorid mit Pyridin, 3-Picolin und Isoquinolin and von n-Propyl(n-butyl)zinn-dichlorid mit Isoquinolin, n-Propylamin and Benzylamin dargestellt und ihre Zusammensetzung aus dem Zinn- und Chlorgehalt bestimmt. IR-Messungen (4000-200 cm-1) weisen darauf hin, daß in allen hexakoordinierten Komplexen des Methylethyl-zinn-dichlorides die Chloratome in eis-Position stehen. Im Fall der hexakoordinierten Komplexe des Ethyl(n-propyl) und n-Propyl(n-butyl)zinn-dichlorides jedoch kann die mehrfache Aufspaltung der Zinn-Chlorvalenzbande auf dem Vorliegen von Konformationsisomeren beruhen. Leitfähigkeitsmessungen wurden zur Bestimmung des Ionencharakters ausgeführt.
    Notes: Complexes of methylethyltin dichloride with 3-, 4-picolines, isoquinoline and benzyl amine, of ethyl(n-propyl) tin dichloride with pyridine, 3-picoline and isoquinoline and of n-propyl (n-butyl)tin dichloride with isoquinoline, n-propyl amine and benzyl amine have been prepared and their stoichiometries established from their tin and chlorine contents. I.R. measurements (4000-200 cm-1) suggest that in all the hexa-coordinated complexes of methylethyltin dichloride, the chlorines are in cis-position. In case of hexa-coordinated complexes of ethyl(n-propyl)- and n-propyl (n-butyl) tin dichlorides, however, the multiple splitting of tin-chlorine stretching band may also be due to the presence of conformational isomers. The conductance measurements have also been carried out to determine their ionic character.

    Description / Table of Contents: Es wird über Herstellung und Eigenschaften von NiII- und CuII-Komplexen mit der SCHIFFschen Base „BAPE“ aus Acetophenon und Äthylendiamin sowie über gemischte BAPE/Acetylaceton-Komplexe berichtet (Formeln I-V s. Abstract). BAPE wirkt dabei als zweizähniger Neutralligand. Die Komplexe wurden durch Elementaranalyse, Elektronenspektrum sowie durch magnetische und Leitfähigkeitsmessungen charakterisiert. Für MII(BAPE)Cl2 wird pseudotetraedrische, für [MII(BAPE)(acac)(H2O)2] ClO4 tetragonale Struktur abgeleitet (MII = Ni, Cu). Der Komplex [Ni(BAPE)(acac)]ClO4 erwies sich als quadratisch-planar.
    Notes: Preparation and properties of the following NiII and CuII complexes of the Schiff base derived from acetophenone and ethylenediamine (BAPE) and also of the mixed NiII and CuII chelates with BAPE and acetylacetone (acac-H) are described: In each case the Schiff base, BAPE, acts as a neutral bidentate ligand. The complexes are characterised by electronic spectra, magnetic susceptibilities, conductivities and elemental analyses. Pseudotetrahedral structure is proposed for M(BAPE)C12, while tetragonal structure for [M(BAPE)(acac)(H2O)2]ClO4 (M = Ni and Cu). The complex [Ni(BAPE) (acac)]ClO4 has been found to be square planar.

    Notes: Die Zusammensetzung des Niederschlages, der bei Zusatz von Silbernitrat- zu einer Chromatlösung ausfällt, hängt vom PH der Chromatlösung und von den Konzentrationen der Ausgangslösugen ab. Obwohl sie sich unter bestimmten Bedingungen der Formel Ag2Cr2O7 nähert, kann diese Verbindung aus wäßriger Lösung nicht rein dargestellt werden.

    Notes: The vibrational spectrum of N-trimethylborazine, (-BH-NCH3-)3, has been recorded in the 200 to 4000 cm-1 region and an assignment of the fundamentals is proposed. The data are supported by a study of the spectra of several isotopically labeled N-trimethylborazines and compare favorably with a normal-coordinate analysis of the molecule.
