The organoaluminium and -gallium acetonoximates (tBu2MON=CMe2)2 (M = Al, Ga) have been prepared by the reaction of acetoneoxime with tri-tert-butylaluminium and -gallium. The compounds (Me2MON=CMe2)2 (M = Al, Ga), described previously, were synthesized for comparison. All compounds have been characterised by NMR spectroscopy (1H, 13C, 27Al), by mass spectrometry and elemental analyses. The crystal structures of the four compounds have been determined, and it was shown that all form dimers with six-membered M2O2N2 rings by aggregation through the imino N atoms. The compounds (Me2MON= CMe2)2 adopt boat conformations, whereas the compounds (tBu2MON=CMe2)2 prefer chair conformations. Large differences in the M-O-N angles have been found between the methyl and the tert-butyl analogues.
