The radical anion of cyclopentasilane-fused hexasilabenzvalene was synthesized by the reduction of the corresponding neutral compound. X-ray crystallographic analysis showed a more trans-bent structure of the disilene moiety than the neutral compound. Theoretical calculations showed that the highly trans-bent structure is attributed to the hexasilabenzvalene structure. The EPR spectrum showed that an unpaired electron exists mainly at the disilene moiety. In the UV/Vis spectrum, a large bathochromic shift was observed compared with the neutral compound.
通过还原相应的中性化合物合成了环戊硅烷稠合六硅苯并戊搭烯的自由基阴离子。X射线晶体学分析表明，与中性化合物相比，二硅烯部分具有更明显的反式弯曲结构。理论计算表明，高度反式弯曲结构归因于六硅苯并戊搭烯结构。电子顺磁共振光谱表明，未成对电子主要存在于二硅烯部分。在紫外/可见光谱中，与中性化合物相比观察到较大的红移。
