Abstract
The integrated intensity ( A) of GeH stretching modes in IR spectra of 30 trisubstituted germanes (R i) 3GeH, has been studied. For R 3GeH compounds in which the R substituents do not form d π p π bonds with the germanium atom, the correlation between A 1/2 and the sum of inductive Σσ* constants of the R i substituents has been established. The contributions made by conjugation effects of a germanium atom with the R i substituents to the integrated intensity of v(GeH) bands are estimated. The formation of weak labile complexes of ( p → d)σ triorganogermanes with carbon tetrachloride has been studied. The values of v(GeH) intensity are compared with the data on disubstituted germanes (R i) 2GeH 2 and silane derivatives (R i) 3SiH.
