Abstract

The ligands aminobis(N-ethylenesalicylidenimine) (SalenN₃H₃) and aminobis(N-propylenesalicylidenimine) (SalpenN₃H₃) were used to form the bimetallic complexes SalenN₃H{AlMe₂}₂ (1), SalpenN₃H{AlMe₂}₂ (2), SalenN₃H{AlMeCl}₂ (3) and SalpenN3H{AlMeCl} (4). When extracted in THF 3 and 4 redistribute to form the ionic compounds [SalenN₃H{Al(THF)}]⁺ [AlMe₂Cl₂]^- (5) and [SalpenN₃H{Al(THF)}]+ [AlMe₂Cl₂]^- (6). The compounds were characterized by Mp analyses, ¹H-NMR and IR, and in the case of 2 and 6 by X-ray crystallography. Additionally, the potential of 5 and 6 to serve as propylene oxide polymerization catalysts was examined.
