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.
