The coordinative interaction of a diorganotin dihalide with N-(meta-substituted phenyl)-2-hydroxynaphthalideneimine
摘要:
The reaction of 1-[3'-methoxyphenylimino)methyl]-2-naphthol with dimethyltin(IV) dichloride yields an addition compound having 2:1 stoichiometry (ligand: organotin). The complex formed has been characterized by elemental analysis, H-1 and C-13 NMR spectroscopy, IR spectroscopy and X-ray analysis. Coordination of the Schiff base to the metal occurs via the phenolic oxygen atom. This preferred mode of bonding is associated with the shift of the phenolic proton towards the azomethine atom resulting in a zwitterionic configuration for the ligand.
