Abstract

The gallium sulphide cubane compounds [(Me2EtC)GaS]4 and [(Et2MeC)GaS]4, have been synthesised, and their potential as MOCVD precursors for GaS is discussed. The molecular structure of [(Et2MeC)GaS]4 has been determined by X-ray diffraction. In addition, the vapour phase structure of the GaSe precursor, [(tBu)GaSe]4 has been determined by gas phase electron diffraction and is compared with that previously determined in the solid state by X-ray diffraction.
