  摘要：

  我们合成了一种新的三二硫环烯钒（IV）络合物，并对其进行了表征。对映体阴离子单元[V(dbddto)3]2-紧密排列，富硫平面配体堆叠形成蜂巢片状结构，从而为客体创造了大空腔（12 × 5.5 Å）。磁感应强度显示，尽管钒离子的原子间距较大（V--V 间距 = 11.069 Å（平均值）），但仍存在反铁磁性相互作用，这与蜂巢片中堆积配体通路之间的相互作用有关。

  Alkylthio-substituierte Bis(benzol-1,2-dithiolato)zinkate, Benzol-1,2-dithiole und -1,2-dithiolate - Edukte f�r Dibenzo[c,g](1,2,5,6)tetrathiocine und Benzo[c](1,2,3)-trithiole; Untersuchungen zu Benzodithieten und ortho-Dithiobenzochinonen

  摘要：

  Using benzenehexathiolate 1 it is possible to synthesize alkylthio-substituted benzo-1,3-dithiole-2-thiones 2, or -ones 3 and benzo-di(1,3-dithiole-2-thiones) 4, or -ones 5, resp., which were cleaved under basic conditions. The generated benzene-1,2-dithiolates 7 were isolated as benzenedithiolato zincates 8, benzene-1,2-dithioles 11, and benzene-1-thiole-2-thiolates 10. Dibenzo[c,g](1,2,5,6)-tetrathiocins 9 were synthesized by oxidation of 7 or 8 in good yields. For the per(methylthio)-substituted tetrathiocin 9a the twist conformation was proved by x-ray structure analysis.The tetrathiocin 9a was probably formed via the orthodithiobenzoquinone 13a. Photolysis of 3a at room temperature in solution led to 9a and tetrakis(methylthio)benzo[c] (1,2,3)trithiole 12a as the main product, which was also formed by irradiation of 9a. The trithioles 12 were formed from 8 by reaction with sulfur dichloride. 12a was investigated by x-ray structure analysis. ortho-Dithiobenzoquinone 13c can be claimed as an intermediate upon irradiation of benzo-1,3-dithiol-2-one 3c in an argon matrix at 10 K. Depending on the wavelength the equilibrium lies either on the side of dithiobenzoquinone 13c or benzodithiete 14c. The same is true for system 15/16, which can be reached by flash vacuum pyrolysis of 3c.
