Organogermanium compounds analysis

See introductory remarks in Section I.A.4. Table 3 summarizes examples of crytallo-graphic analysis published in the recent literature, with brief comments about structural features of organogermanium compounds.

The Ge NMR chemical shifts of several methyl-and phenyl-substituted germacyclohexanes have been determined, and it has been shown that the chemical shifts are very sensitive to steric effects and can provide a useful tool for the conformational analysis of organogermanium compounds. 

Several volatile organogermanium hydrides have been studied, principally to compare their barrier to internal rotation about the Ge—C bond with the analogous C—C and Si—C compounds. Although analysis of the microwave spectroscopic data which predominate in these studies often requires one or more of the molecular parameters to be assumed, the data taken as a whole indicate a number of trends in the bonding of these simple tetrahedral molecules (Table I).
