    Description / Table of Contents: (tBu)2N2Se6 and (tBu)6N6Se9: Synthesis and Structure of two Stable Eight- and Fifteen-membered Nitrogen-Selenium RingsDiselenium dichloride, Se2Cl2, and seleninyl chloride, SeOCl2, react with the lithium salt 1 of silylated tert-butylamine with elimination of LiCl and Me3SiCl or of LiCl, Me3SiCl, and (Me3Si)2O, respectively, to form the cyclic compounds hexaselenadiazocin 2 and nonaselenahexaazacyclopentadecane 3. The structures were established by X-ray analysis. 2 crystallises in the space group P421m with a conformation of the N2Se6 ring similar to that of the eight-membered ring of the sulfur molecule. 3 crystallises in the space group C2/c.
    Notes: Diselendichlorid, Se2Cl2, bzw. Seleninylchlorid, SeOCl2, reagieren mit dem Lithiumsalz 1 des silylierten tert-Butylamins unter Abspaltung von LiCl und Me3SiCl bzw. von LiCl, Me3SiCl und (Me3Si)2O zu den cyclischen Verbindungen Hexaselenadiazocin 2 und Nonaselenahexaazacyclo-pentadecan 3. Die Konstitutionen werden durch Röntgenstrukturanalyse gesichert. 2 kristallisiert in der Raumgruppe P421m mit einer dem achtgliedrigen Schwefelmolekül ähnlichen Konformation des N2Se6-Ringes. 3 kristallisiert in der Raumgruppe C2/c.

    Description / Table of Contents: Synthesis, Structure, and Some properties of 1,2,3-Benzodithiazolium Salts4,6,7a-Tri-tert-butyl-7aH-1,2,3-benzodithiazole (3) reacts with phosphorus pentachloride with elimination of tert butyl chloride to form benzodithiazolium chloride 4a. The chloride 4a reacts with SbCl5 and AgAsF6 to yield the hexachloroantimonate 4b and the hexafluoroarsenate 4c, respectively. The structure 4b was established by an X-ray analysis. 4b crystallizes in the space group P21/c with a=1243.9(2), b=1525.6(2), c=1255.7(2) pm, β=102.86(1)° and V=2323(1) · 106 pm3. The structure consists of isolated [C14H20NS2]+ cations and [SbCl6]- anions. The cation is planar within experimental accuracy.
    Notes: 4,6,7a-Tri-tert-butyl-7aH-1,2,3-benzodithiazol (3) reagiert mit Phosphorpentachlorid unter tert-Butylchloridabspaltung zum Benzodithiazoliumchlorid 4a. Das Chlorid 4a läßt sich mit SbCl5 und AgAsF6 in das Hexachloroantimonat 4b und Hexafluoroarsenat 4c überführen. Die Konstitution 4b wird durch Röntgenstrukturanalyse gesichert. 4b kristallisiert in der Raumgruppe P21/c mit den Gitterkonstanten a = 1243.9(2), b = 1525.6(2), c = 1255.7(2) pm, β = 102.86(1)° und V = 2323(1) · 106 pm3. Die Struktur besteht aus isolierten [C14H20NS2]+-Kationen und [SbCl6]--Anionen. Das Kation ist innerhalb der Meßgenauigkeit planar gebaut.
