    Description / Table of Contents: Synthesis and Structure of Bis(3-diethylamino-5-phenyl-1,2,4-dithiazolium)-tetrachlorocobaltat(II)The title compound 1 was prepared by reaction of Tris(1,1-diethyl-3-benzoyl-thioureato)cobalt(III) with SOCl2 in acetonitrile. 1 has been characterized by IR-spectroscopy and VIS-spectroscopy.The structure of 1 has been determined by an X-ray structure analysis. The compound crystallizes in the monoclin space group C2/c with a = 16.224; b = 11.257; c = 17.697 Å; β = 107,43° and Z = 4. The final R value was R = 0.027 for 2073 observed reflections.The cation of 1 is nearly plane with an extended delocalization of electrons. The CoCl42- anion is tetrahedral with two different long Co—Cl pairs. Interionic contacts S … Cl exists between the structural units of the cations and the anion.
    Notes: Die Darstellung der Titelverbindung 1 erfolgt aus Tris(1,1-diethyl-3-benzoyl-thioureato)-cobalt(III) mit SOCl2 in Acetonitril. 1 wird IR-spektroskopisch und durch VIS-Spektren charakterisiert.Die Struktur von 1 wurde durch Röntgenkristallstrukturanalyse bestimmt. Die Verbindung kristallisiert monoklin in der Raumgruppe C2/c mit den Gitterkonstanten a = 16,224; b = 11,257; c = 17,697 Å, β = 107,43° und Z = 4. Der abschließende R-Wert betrug R = 0,027 für 2073 beobachtete Reflexe.Das Kation von 1 ist nahezu planar und weist eine weitreichende Elektronendelokalisierung auf. Das CoCl42--Anion ist tetraedrisch strukturiert und besitzt zwei unterschiedlich lange Co—Cl-Paare. Zwischen Kation- und Anion-Struktureinheiten bestehen über S und Cl interionische Wechselwirkungen.
