Abstract
The addition of 4-methylpyridine to Me2Al[OC(Me) C6H4-2-O] produced the rel atively stable five-coordinate Lewis acid-base adduct Me2Al [OC(Me)C6H4-2-O ] . (gamma-picoline). The resulting compound has been characterized by H-1 and Al-27 NMR spectroscopy and cryoscopic molecular weight measurements and the molecular structure has been confirmed by X-ray crystallography. X-ray structure analysis of this simple five-coordinate complex reveals that the trans-influence of axial substituents is a significant factor controlling the structure and stability of five-coordinate aluminum compounds.
