✦ Synopsis

The title compound, [Al(C~2~H~5~)(C~31~H~28~O~4~)(C~4~H~8~O)], has a slightly distorted tetrahedral geometry around the Al^III^ metal centre. The bidentate TADDOLate ligand and the Al^III^ metal atom form a seven-membered ring, with an O—Al—O angle of 111.19 (10)°, which is close to the ideal tetrahedral 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 Al^III^ metal centre.
