✦ Synopsis
Treatment of GaMe 3 with one equivalent of HO c Hex in toluene at 20 °C leads to [Me 2 GaO c Hex] 2 (4) under evolution of methane. The reaction of InMe 3 with two equivalents of HO c Hex leads under similar conditions not to [MeIn(O c Hex) 2 ] n but to the sesquialkoxide [In{Me 2 In(O c Hex) 2 } 3 ] (5). 5 can be described also as [{Me 2 InO c Hex)} 2 {MeIn(O c Hex) 2 } 2 ]
. The use of an excess of cyclohexanol in boiling toluene gives the same result. Under these reflux conditions, the reaction of GaMe 3 with an excess of PhCH 2 OH leads exclusively to another type of sequialkoxides, [Ga{MeGa(OCH 2 Ph) 3 } 3 ] (6). 4 Ϫ 6 were characterized by NMR, vibrational and MS spectra, as well as by X-ray structure determinations. According to this, 4 forms centrosymmetrical and therefore
