The reaction of β-diketiminated aluminum(I) monomer LAl with a large bulky azide N<sub>3</sub>Ar‘ (L = HC(CMeNAr)<sub>2</sub>, Ar‘ = 2,6-Ar<sub>2</sub>C<sub>6</sub>H<sub>3</sub>, Ar = 2,6-<i>i</i>Pr<sub>2</sub>C<sub>6</sub>H<sub>3</sub>) in the temperature range from −78 °C to room temperature affords two different isomers <b>2</b> and <b>3</b>, which have been characterized by spectroscopic and X-ray structural analyses, as well as elemental analysis. The variable-temperature <sup>1</sup>H NMR kinetic studies of this reaction indicate the existence of the monomer LAlNAr‘ (<b>1</b>) at low temperature and the thermal stability of the compounds increases in the order of <b>1</b> < <b>2</b> < <b>3</b>.
