    Description / Table of Contents: Contributions to the Chemistry of Hydrazine and its Derivatives, XLVIII. 2-Amino-1,3-dithia-2-aza-1,1,3,3-cyclohexanetetroneBy the reaction of 1,3-propanedisulfonyl dichloride with hydrazine dihydrochloride and sodium hydroxide the 1,1-disubstituted hydrazine 1b is formed. The preparation of the isomeric compound 1a analogous to the cyclic dicarboxylic acid hydrazides did not succeed. 1b forms with acetic acid the derivative 4 and with benzaldehyde the hydrazone 5. The structure of 1b was determined by X-ray analysis and discussed by means of the data thus obtained.
    Notes: Bei der Umsetzung von 1,3-Propandisulfonyl-dichlorid mit Hydrazinium(2+)-dichlorid und Natronlauge entsteht das 1,1-disubstituierte Hydrazin 1b. Die Darstellung der isomeren Verbindung 1a in Analogie zu den cyclischen Dicarbonsäurehydraziden gelang nicht. 1b bildet mit Eisessig das Derivat 4 und mit Benzaldehyd das Hydrazon 5. Die Struktur von 1b wurde durch Röntgenanalyse bestimmt und anhand der erhaltenen Daten diskutiert.

    Description / Table of Contents: Contributions to the Chemistry of Hydrazine and its Derivatives, LI1 Crystal and Molecular structure of N, N, N′, N′-Tetraaminopiperazindiium Bis(azide)The structure of the title compound 3 was determined by X-Ray analysis. The compound crystallizes in the monoclinic space group P21/c. The six-membered heterocycle of the dication exists in chair conformation. Bond lengths, bond angles, and dihedral angles of this first triazanium salt investigated by X-ray diffraction as well as the NH2… N3 hydrogen bonds in the crystal are discussed.
    Notes: Die Struktur der Titelverbindung 3 wurde durch eine Röntgenanalyse bestimmt. Die Verbindung kristallisiert in der monoklinen Raumgruppe P21/c. Der sechsgliedrige Heterocyclus des Dikations liegt in der Sesselkonformation vor. Bindungslängen, Bindungswinkel und Torsionswinkel dieses ersten röntgenographisch untersuchten Triazanium-Salzes sowie im Kristall auftretende NH2…N3-Wasserstoffbrücken werden diskutiert.
