摘要：

The perfect all-anti-octasilane composed of two bicyclic trisilane units with trimethylsilyl groups at the termini has been synthesized. Its X-ray crystal structure and spectroscopic data demonstrate the effective σ-delocalization over the silicon framework, which is a definitive difference from the unconstrained n-Si8Me18.
