(3-{[2,6-Bis(1-methyl­eth­yl)phen­yl]imino-κN}-1-phenyl­but-1-en-1-olato-κO)­di­methyl­aluminium

The mol­ecular structure of the title compound, [Al(CH₃)₂(C₂₂H₂₆NO)], displays a monomer with the Al^III atom in a distorted tetra­hedral environment defined by two methyl groups and the N and O atoms of the chelating ketiminate anion. The O—Al—N bite angle of the chelating ligand is 94.14 (9)°. The O—C—C—C—N backbone of the ligand is nearly coplanar (r.m.s. deviation = 0.029 Å) and the Al atom deviates significantly from the mean plane by 0.525 (3) Å. In the crystal, weak inter­molecular C—H...O inter­actions are observed.
