Synthesis and Structure of a Digallane with Tris(trimethylsilyl)silyl and Chloro Substituents

Abstract

A cage comprising four gallium and four chlorine atoms (shown on the right) is the characteristic feature of the first dimeric digallane 1 (R = Si(SiMe3)3) having two different substituents. It is synthesized together with the tetrasilyl-substituted digallane 2 from Ga[GaCl4] and LiSi(SiMe3)3(THF)3.
