W. Clegg, M. R. J. Elsegood, R. Snaith and A. E. H. Wheatley

Abstract: The title compound, [Al(C₁₈H₁₃O)₃(C₉H₈O)], crystallizes with three molecules in the asymmetric unit of the chiral trigonal space group P3₂. The three molecules have essentially the same geometry, and are related by non-crystallographic translation and other pseudosymmetry, all being in approximately the same orientation. Aluminium has a typical tetrahedral coordination. Al-O bond lengths range from 1.695  (3) to 1.716  (3)  Å for the bulky substituted phenoxy ligands, and from 1.830  (4) to 1.841  (4)  Å for the neutral trans-cinnamaldehyde ligands.
