monoalkylaluminium complexes (dpp-BIAN)AlR(Et2O) (R = Me, 1; Et, 2; iBu, 3). Compounds 1-3 have been characterized by elemental analysis, IR and 1H NMR spectroscopy. Single crystal X-ray diffraction has been used to determine the molecularstructures of 1 and 2. Both structures show the aluminium atom tetrahedrally coordinated by the two N atoms of the dianionic dpp-BIAN ligand, the alkyl group, and
