precipitates. The average particle size is 17.7 ± 7.4 nm. The tetrametallic core of 1, having the correct stoichiometry for alumina (2Al2O3) appears to act as a template or nucleating site for the formation of alumina rather than the expected products of formula, AlOOH. The stability of the Al4O6 core of 1 was tested by combining it with six equivalents
