    Description / Table of Contents: On Chalcogenolates. 97. Thioxanthates of TungstenThe black-blue coloured alkylthioxanthates of tungsten(IV) W[S2C—SR]4 with R = C2H5, iC3H7, tC4H9 have been prepared by reaction of [(nC4H9)4N]W(CO)5I with the corresponding bis(alkylthioxanthogen). The oxidation of W[S2C—SC2H5]4 with iodine leads to brass coloured W[S2C—SC2H5]4(I5).The careful acidification of an aqueous solution containing [S2C—SC2H5]- and WS42- or WO2S22- ions gives black-green (W2S3[S2C—SC2H5)]4 or olive-green W2O3[S2C—SC2H5]4, respectively.The prepared compounds have been characterized by means of chemical and thermoanalytical methods as well as by infrared spectra, electron absorption spectra, 1H-NMR spectra, and mass spectra.
    Notes: Die schwarzblau gefärbten Wolfram(IV)-alkylthioxanthate W[S2C—SR]4 mit R=C2H5, iC3H7, tC4H9 wurden durch Umsetzung von [(nC4H9)4N]W(CO)5 I mit dem entsprechenden Bis(alkylthioxanthogen) hergestellt. Die Oxydation von W[S2C—SC2H5]4 mit Iod liefert messingfarbenes W[S2C—SC2H5]4(I5).Die Darstellung von schwarzgrünem W2S3[S2C—SC2H5]4 bzw. olivgrünem W2O3[S2C—SC2H5]4 gelang durch vorsichtiges Ansäuern wäßriger Lösungen, die [S2C—SC2H5]--und WS42--bzw. WO2S22- Ionen enthalten.Die hergestellten Verbindungen wurden mit chemischen und thermoanalytischen Methoden sowie mit IR—, UV—, 1H—NMR— und Massenspektren charakterisiert.

    Description / Table of Contents: On Chalcogenolates. 111. Studies on Perthiocyanic Acid. 4. Crystal and Molecular Structure of Dimethyl Perthiocyanate(CH3)2C2N2S3 crystallizes with Z = 4 in the monoclinic space group P21/c with cell dimensions a = 7.661(4) Å, b = 11.675(5) Å, c = 9.549(5) Å, β = 116.7(3)·. The crystal and molecular structure has been determined from single X-ray data at 20°C and refined to a conventional R of 0.062. The structure consists of isolated 3,5-bis(methylmercapto)-1,2,4-thiadiazole molecules. The 1,2,4-thiadiazole ring is plane and stabilized by mesomerism.

Die Struktur wurde aus röntgenographischen Einkristalldaten bei 20°C bestimmt und bis zu einem konventionellen R-Faktor von 0,062 verfeinert. Die Struktur besteht aus isolierten 3,5-Bis(methylmercapto)-1,2,4-thiadiazol-Molekülen. Der 1,2,4-Thiadiazol-Ring ist planar und mesomeriestabilisiert.
