Conformational analyses of a series of neopentyl- and trimethylsilylmethyl-substituted germyl radicals by electron spin resonance(ESR) were investigated on the basis of the modified cos2θ rule.Dimethylneopentylgermyl radical has the conformations with the neopentyl group rotating freely.On the other hand, dimethyl(trimethylsilylmethyl)germyl radical has the preffered conformations with trimethylsilylmethyl group eclipsing with the singly occupied orbital on a germanium atom.The ESR spectra of dineopentylmethylgermyl and bis(trimethylsilylmethyl)methylgermyl radicals showed the existence of two kinds of methylene protons due to th e nonplanar geometries and the slow inversion of these germyl radicals.Conformations of trineopentylgermyl and tris(trimethylsilylmethyl)germyl radicals are also discussed.
