Dialkyltin(IV) difluorides: Synthesis and study of their state in solutions

Dialkyltin difiuorides Bu2SnF2 and Et2SnF2 were synthesized by reacting R2SnO with hydrofluoric acid and heating. Solutions of Bu2SnF2 and Bu2SnCl2 in different organic solvents were studied by 119Sn, 19F, 13C, and 1H NMR spectroscopy. The conclusion is drawn that dialkyltin dihalides partially dissociate in solutions.

THE SYNTHESIS AND TIN-119m MOESSBAUER SPECTRA OF SOME DIORGANOTIN DIHALIDE AND DIPSEUDOHALIDE COMPLEXES WITH NITROGEN AND OXYGEN-DONOR LIGANDS

The synthesis and 119mSn Moessbauer spectra of 114 complexes of the type R2SnX2, L2 (R = Me, Et, n-Pr, n-Bu, n-Oct, Ph, Bz; X = F, Cl, Br, I, NCS; L2 = 2 monodentate or 1 bidentate O- or N-donor ligand(s)), 74 of which are new, are reported.The majority of the complexes are isostructural, having an octahedral trans-R2SnX4 geometry about tin, whilst five of the diphenyltin complexes (R = Ph; X = Cl; L2 = AMP, Nphen; X = NCS; L2 = bipy, phen, TMphen) adopt a cis-R2SnX4 octahedral structure.A convenient method for the synthesis of a number of novel 1:1 diorganotin difluoride complexes using hot acetonitrile is reported and a structure for the unusual adduct, Ph2SnF2 * 0.5 phen, is proposed.
