The group 13 monoalkoxometallanes [MeGa(OC(CH) CHOMe)] (1) and [Me In(OCH(CH)CHOMe)] (2), incorporating donor functionalised alkoxides, were synthesised from the reaction of GaMe or InMe with ROH (R=C(CH) CHOMe (1); R=CH(CH)CHOMe (2)) in toluene. X-ray crystallography showed that both compounds adopt dimeric structures with a planar MO ring, and each group 13 atom is coordinated in a distorted trigonal bipyramidal geometry. The AACVD reaction of GaMe and ROH (R =C(CH)CHOMe, CHCHOMe, CHCHNMe) resulted in the formation of thin films of GaO on glass substrates at 450°C. The gallium oxide films were analyzed by scanning electron microscopy, X-ray powder diffraction, energy dispersive analysis of X-rays, wavelength dispersive analysis of X-rays and X-ray photoelectron spectroscopy. This CVD technique offers a rapid, convenient route to Ga O, which involves the in situ formation of dimethylgallium alkoxides, of the type [MeGa(μ-OR)] similar to compound 1. © 2010 - IOS Press and the authors.
