摘要

The σ- and π-electron effects of alkyl/phenyl substituents on the Sn-Hal bonds in penta- and hexacoordinate tin(Ⅳ) chloro and iodo adducts are discussed based on their ~(35)Cl and ~(127)I NQR spectra. Unexpectedly high ~(127)I EFG asymmetry parameters were found in most dialkyl(phenyl)-substituted adducts of thin(Ⅵ) iodides.
