Unusual structures and bonding situations characterize the homopolyatomic cations of the non-metals, which are of fundamental importance to the chemistry of these elements. While classical syntheses to those cations have been studied exhaustively, modern concepts and methods represent promising new access paths. In this project the homopolyatomic cations of the elements of group 16 (sulfur, selenium, tellurium) will be investigated. Furthermore, these methods will be transferred to selected elements of groups 15 (phosphorus, arsenic, antimony) and 17 (bromine). In condensed phase the cations will be stabilized by halogenated weakly coordinating boron cluster-based anions. It is expected that these large and weakly coordinating anions also stabilize radical cations, besides dications, of the non-metal elements. The synthetic studies will be accompanied by EPR-spectroscopic, electrochemical, and quantum-chemical investigations.

不寻常的结构和成键情况表征了非金属的均多原子阳离子，这对这些元素的化学具有重要意义。虽然对这些阳离子的经典合成已经进行了详尽的研究，但现代概念和方法代表了有希望的新途径。本项目将研究16族元素（硫、硒、碲）的均多原子阳离子。此外，这些方法将转移到第15族（磷、砷、锑）和第17族（溴）的选定元素。在缩合相中，阳离子会被卤化弱配位硼簇基阴离子稳定。预计这些大而弱配位的阴离子除了能稳定非金属元素的自由基外，还能稳定自由基。合成研究将伴随着epr光谱、电化学和量子化学的研究。
