A Study of Germanium Hydrides, Anions and Related Species

Abstract

<p> The relative acidities of some aryl germanes have been measured in liquid ammonia.</p> <p> The NMR spectra of phenyl silane and phenyl germane have been completely analysed and the chemical shifts shown to arise from the presence of an electric dipole in the molecule. The NMR spectrum of phenyl germyl anion was unambiguously assigned and partially analysed. The results are consistent with little delocalization of the negative charge from the Ge onto the ring.</p> <p> The vibrational spectra of the germyl anion have been observed and the geometry of the molecule estimated from a normal coordinate analysis of the data.</p> <p> The Raman spectrum of liquid ammonia-D3 has been measured and two bands in the Raman spectrum of liquid ammonia have been reassigned.</p>
