The 13C and 119Sn NMR spectra of some four- and five-coordinate tri-n-butyltin(IV) compounds

The 13C and 119Sn NMR spectra of a set of tri-n-butyltin(IV) compounds and their complexes in coordinating and non-coordinating solvents have been studied. The chemical shifts δ( 119Sn) and δ( 13C) and the coupling constants 1 J( 119Sn 13C) depend significantly on the coordination number of the tin...

Summary:The 13C and 119Sn NMR spectra of a set of tri-n-butyltin(IV) compounds and their complexes in coordinating and non-coordinating solvents have been studied. The chemical shifts δ( 119Sn) and δ( 13C) and the coupling constants 1 J( 119Sn 13C) depend significantly on the coordination number of the tin atom and on the geometry of its coordination sphere. Approximate ranges of these characteristic NMR parameters for various types and configurations of tri-n-butyltin(IV) compounds have been defined. The data for these compounds are discussed in comparison with those for triphenyltin(IV) compounds.
