N2 - A wide range of bimetallic aluminum molecules are formed in combinations between Salen Schiff base ligands and either AlR3 or AlR2Cl. They are of the general formulas L(AlR2)2 and L(AlRCl)2 with R = alkyl and L = Salen(tBu) ligand with relatively unusual `backbone' connections between the nitrogen atoms, 1,2-cyclohexylene (Salcen(tBu)), 1,4-butylene (Salben(tBu)), 1,5-pentylene (Salpten(tBu)), 1,6-hexylene (Salhen(tBu)), and 1,4-phenylene (1,4-Salophen(tBu)). Additionally, previously unknown ligands were employed with the `backbones' 1,4-bis(p-aminobenzyl)benzene (Salmaben(tBu)), 1-(m-aminobenzoyl)-4-(m-aminobenzyl)benzene (Salmabmaben(tBu)), and 4,4′-bis(m-aminobenzoyl)diphenylmethane (Salmadmen(tBu)). The ligands for these compounds were designed to feature two group 13 sites at long and varying distances from one another. The compounds were characterized by mp analyses, IR, and 1H NMR, and X-ray structures were determined for the examples R,R′-Salcen(tBu){AlMe2}2 (1), Salben(tBu){AlMe2}2 (2), 1,4-Salophen(tBu){GaEt2}2 (7), R,R′-Salcen(tBu){AlMeCl}2 (11), Salben(tBu){AlMeCl}2 (13), and Salhen(tBu){AlMeCl}2 (14).
