The present work describes the synthesis and characterization of a series of complexes of formula LAlR(AlR2)2(R = Et, L = Salean (1), Salpan (2), Salophan (3), Salomphan (4); R = iBu, L = Salean (5), Salpan (6), Salophan (7), Salomphan (8)). The use of the comparatively bulky iBu group in 5 results in a complex which adopts a cis ligand configuration as shown by an X-ray structural analysis. The trimetallic complexes display 1H NMR spectra that are consistent with a rigid solution-state geometry. The presence of a deshielding interaction between the protons on the alkyl group 13 reagent and the arylamine backbones of the Salophan and Salomphan ligands will be discussed. Additionally, the crystal structures of SalophanGaMe(GaMe2)2 (9) and SalomphanGaMe(GaMe2)2 (10) are reported.
