Germanium Trimers

Cyclic, trimeric germanium compounds containing the unit Ge3R3 are of two types the cationic (GeR)3+ [33] species and the neutral radical (GeR)3 [34]. The [Pg.194]

As for dihalogermanes having relatively bulky ligands (2,6-dimethylphenyl or 2,6-diethylphenyl) on the germanium atom, the chain elongation may proceed to give a trimeric compound 19. The steric congestion due to the substituents used forces the... [Pg.846]

Germanium analogs of cyclosUoxanes reported to date include (R2GeO) trimers and tetramers (e.g. with R = Me, Et, Pr, Ph, etc.) but they did not attract as much interest as their silicon relatives. ... [Pg.5999]

If the cyclic trimer (9.316) is heated, pentameric phenylphosphine is obtained (9.326). Like their silicon and germanium analogues, stannyl phosphines are easily hydrolysed (9.327), or oxidised to phosphinates (9.328). The P-Sn bond is broken by alkyl halides as in Equation 9.329. [Pg.758]
