  Torsional distortions in trimesitylsilanes and trimesitylgermanes

  摘要：

  The crystal structures have been solved for allyltrimesitylsilane (3), trimesitylsilane (4), and trimesitylgermane (5). Steric congestion caused by the three mesityl groups causes some lengthening of the Si-C and Ge-C bonds. The C-Si-C and C-Ge-C bond angles are increased when X is not H. Distortion is relieved by rotating the plane of the phenyl rings to create a propeller conformation. The same distortion has been found in unpublished data of the reported crystal structures of trimesitylsilyl azide (6) and aminotrimesitylgermane (7). Despite the variety of substituents (allyl, amino, azido, H) and the two different central atoms (Si, Ge), the twist angle of the propeller (compared with a conformation lacking any twist) lies between 41.6 and 48 degrees for all five systems.
