Adduct of AlMe₃ with Benzo[f]quinoline

The reaction of AlMe₃ with 5,6-benzo[f]quinoline gave the Lewis acid-base adduct Me₃Al-BQ, (BQ = benzo[f]quinoline) {(benzo[f]quinoline-N)trimethylaluminium, [Al(CH₃)₃(C₁₃H₉N)]}, with an Al-N bond length of 2.057 (2) Å. This adduct is much less air and water sensitive than the trialkyl metal. The complex was found to be a discrete 1:1 molecular adduct of trimethylaluminium bonded to BQ. The compound contains a tetracoordinate Al atom with distorted tetrahedral geometry.
