silabenzene and silacyclopropabenzenes were synthesized by taking advantage of an efficient steric protection group, 2,4,6-tris[bis(trimethylsilyl)methyl]phenyl (Tbt). The molecular geometries of these novel conjugated ring systems containing a silicon atom were definitively determined by X-ray crystallographic analysis. Their spectral data such as 1H, 13C, and 29Si NMR, FT-Raman, and UV-vis spectra and
