Synthesis, Reactivity and Spectral Studies of Some Pentacoordinate Tin(IV) Complexes Derived from Triphenyltin Trifluoroacetate
Srivastava, T. N.,Singh, Jai Deo
, p. 489 - 492 (2007/10/02)
Triphenyltin methoxide/ethoxide prepared in situ reacts with trifluoroacetic acid, yielding triphenyltin trifluoroacetate in quantitative yield.The reactions of Ph3SnOCOCF3 with tetraalkylammonium salts (R4NX) give pentacoordinated Sn(IV) complex anions of the general formulae (+)(-) .Ph3SnOCOCF3 undergoes cleavage with electrophilic reagents such as ICl, IBr, HgCl2, Hg(SCN)2, yielding Ph2Sn(OCOCF3)*X (X=Cl, Br, SCN).These compounds like the parent Ph3SnOCOCF3 are polymeric in nature with five coordinated Sn(IV) atoms and bridging trifluoroacetate groups.These undergo nucleophilic substitution of (X) with other electronegative groups and form 1:1 molecular adducts with common Lewis bases.All these compounds have been characterized by elemental analyses, and IR and PMR data.
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.
