Description |
The reaction of LiGaMe4 with diphenysilanediol in THF at 50 degreesC leads to the formation of the title gallosiloxane Li-2(Li(THF)(2))(2)[Ph2SiO2GaMe2](2)[Ph2SiO2GaMe(OH)](2). 2THF (1), which is made up of a central tetraanionic G alpha 4Si4O8 16-membered macrocyclic core. The cavity that is created by this tetraanionic gallosiloxane ring and also the presence of two Ga-OH groups pointing toward the center of the macrocyclic ring facilitate the entrapment of two lithium cations in the core through two Li-O(siloxide) and true Li-OH(Ga) linkages. The other two lithium ions are located at the periphery and are bound to the gallosiloxane ring through the Li-O(Si) linkages. Compound 1 represents the first organic-soluble molecular model compound for the S8R secondary building unit of several gallo- and aluminosilicates.
