The title compound, [Al(C2H5)(C31H28O4)(C4H8O)], has a slightly distorted tetra-hedral geometry around the AlIII metal centre. The bidentate TADDOLate ligand and the AlIII metal atom form a seven-membered ring, with an O - Al - O angle of 111.19 (10)°, which is close to the ideal tetra-hedral angle. The Al - O - C(alkoxide) angles of 139.17 (17) and 137.95 (17)° are larger than the sp 3 bond angle, suggesting substantial π-donation of the alkoxide O atom to the AlIII metal centre.
