摘要：
Remarkable properties characterize organosilicon compounds like 1 and 2:some of their structures are distorted by steric overcrowding and their first ionization energies drop as a result of additional radical cation stabilization to unexpectedly low values. In the pi-radical anion of 2 considerable spin delocalization in the SiSi3 frameworks is detected by ESR ENDOR spectroscopy. [GRAPHICS]
