摘要:
The reactions of SnCl2, SnCl4, RSnCl(3), R(2)SnCl(2) and R(3)SnCl (where R = Me and Ph) with 1-[(4-methylphenylimino)methyl]-2-naphthol (L) resulted in the formation of a series of adducts of which the tin : ligand ratio was either 1 : 1 or 1 : 2. The Ph(3)SnCl . 3/2L adduct contains an additional uncoordinated ligand co-crystallized between two tin moieties. All adducts exhibit Sn-O coordination, whilst the divalent tin adduct is further stabilized by an additional Sn-N bond. An X-ray crystal structure analysis of the trimethyltin (IV) derivative is reported.
