Abstract
Blue‐black trisupersilyldigallanyl, a new metastable inorganic radical, forms in the reaction of GaCl3 with tBu3SiNa in pentane at room temperature according to Equation (a). The X‐ray structure analysis reveals that it contains a planar Si2GaIIGaI and a nearly linear GaIIGaISi framework; according to the ESR spectrum the unpaired electron resides in both Ga atoms. Surprisingly, the analogous reaction of AlCl3 and tBu3SiNa (Al instead of Ga in Equation (a)) does not lead to trisupersilyldialanyl, but to red tetrasupersilyldialane (tBu3Si)2Al–Al(SitBu3)2.
