The reaction of compounds containing Al-Mg and Al-Zn bonds with N 2 O enabled isolation of the corresponding Al(μ-O)M complexes. Electronic structure analysis identified largely ionic Al-O and O-M bonds, featuring an anionic μ-oxo centre. Reaction with CO 2 confirmed that these species correspond to the proposed intermediates in the formation of μ-carbonate compounds.
