Abstract

A trichlorogermanide of formula (I): [R 4 N]/[R 4 P]Cl[GeCl 3 ] (I), where R is Me, Et, iPr, nBu, or Ph, tris(trichlorosilyl)germanide of formula (II): [R 4 N]/[R r P][Ge(SiCl 3 ) 3 ] (II), where R is Me, Et, iPr, nBu, or Ph, a tris(trichlorosilyl)germanide adduct of GaCl 3 of formula (III): [Ph 4 P][Ge(SiCl 3 ) 3 *GaCl 3 ], and a tris(trichlorosilyl)germanide adduct of BBr 3 of formula (IV): [Ph 4 P][Ge(SiCl 3 ) 3 *BBr 3 ]. Also, methods for preparing the trichlorogermanides of formula (I), the tris(trichlorosilyl)germanide of formula (II), the tris(trichlorosilyl)germanide adduct of BBr 3 of formula (IV).

First claim

The invention claimed is:

1. A method for preparing a trichlorogermanide, the method comprising:
dissolving GeCl 4 with hexachlorodisilane in a solvent; and
reacting in the presence of a stoichiometric amount of [R 4 N]/[R 4 P]Cl at a temperature of 5 to 40° C.,
wherein the trichlorogermanide is a compound of formula (I):
[R 4 N]/[R 4 P][GeCl 3 ]  (I),

wherein R=Me, Et, iPr, nBu, or Ph.
