  摘要：

  Cationic technetium(III) complexes containing both tetradentate thioether and monothioles, [Tc(''S4'')(SR)2]PF6 (''S4'': 3,6,9,12-tetrathiatetradecane, 5,8,11,14-tetrathiaoctadecane; SR : monodentate thiolates), were prepared starting from TcO4- and characterized by elemental analysis and spectroscopic methods. Bis(benzenethiolato)(5,8,11,14-tetrathiaoctadecane)technetium(III)hexafluorophosphate was characterized by single-crystal X-ray structural analysis (R = 0.084). In the complex the technetium is centred in a heavily distorted octahedron. The benzenethiolate ligands are coordinated in the cis-configuration.

  聚亚烷基硫化物的热降解

  摘要：

  已经研究了聚硫醚和合适的模型化合物的热稳定性。在高于200°C的温度下，聚合物迅速分解，主要形成杂环产物以及直链硫化合物，硫化氢和烯烃。在分析由模型化合物热分解形成的产物的基础上，提出了可能发生大量分解的两种机理。

  The thermal stabilities of polyethylene sulphide and suitable model compounds have been examined. At temperatures greater than 200° the polymers rapidly decompose to afford, in the main, heterocyclic products together with linear sulphur compounds, hydrogen sulphide, and olefins. Based on the analysis of products formed from the thermal breakdown of model compounds two mechanisms by which massive decomposition
