all-anti-octasilane: conformation control of silicon chains using the bicyclic trisilane as a building block
Abstract
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 sigma-delocalization over the silicon framework, which is a definitive difference from the unconstrained n-Si8Me18.
