Organotin(IV) sulphides (LSnPhS)2 (3) and (LSnPh2)2S (4) containing O,C,O chelating ligand (L = 2,6-(t BuOCH2)2C6H3-) were prepared by the reaction of parent organotin chlorides LSnPhCl2 (1) and LSnPh2Cl (2) with Na2S · 9H2O in toluene/water. Both sulphides were characterized by the help of elemental analysis, ESI-mass spectrometry, 1H, 13C 119Sn NMR spectroscopy and the molecular structure of 3 was determined by X-ray diffraction techniques. Compounds 3 and 4 react with I2 to organotin iodides LSnPhI2 (5) and LSnPh2I (6), instead of intended iodolysis of phenyl groups. Triorganotin iodide 6 reacts with the additional molecule of I2 forming an ionic organotin compound [ LSnPh2]+ I3- (7), which is unstable in solution and decomposes to Ph2SnI2 and 2,6-(tBuOCH2)2C6H3I (8).

New bis-o-benzosemiquinonato tin(IV) complexes (3,6-SQ) 2SnCl2, (3,6-SQ)2SnBr2 and (3,6-SQ)2SnPh2 (3,6-SQ is radical-anion 3,6-di-tert-butyl-o-benzosemiquinone) were synthesized by differen

The first examples of compounds containing the [SnR2I3]- anion, i.e. [Bun4N][SnR2I3] (R = Me or Ph), have been prepared and characterized by IR, Raman and 119Sn Moessbauer spectroscopies, and X-ray powder diffraction data. The experimental data are consistent with a trigonal bipyramidal structure, with the R groups in equatorial positions, for the [SnR2I3]- anions. Octahedral [SnR2I4]2- anions could not be isolated and it is shown that the previously reported [Bun4N]2[SnMe2I4] is actually a 1:1 mixture of Bun4NI and [Bun4N][SnMe2I3]. The X-ray powder structure of Cs2SnI6 has been refined by the Rietveld method. The compound crystallises in the cubic Fm3m space group with a = 11.6410(3) A and a Sn-I distance of 2.864(1) A. The Sn-I distances in Cs2SnI6, SnI4(bipy), SnI4(Ph3PO)2 and SnI4(Ph2SO)2 are related to the Moessbauer quadrupole splitting, showing that ligands that are weaker donors than I- (i.e. have a more positive partial quadrupole splitting) give rise to Sn-I distances that are shorter than for the [SnI6]2- anion.

The reaction of polymeric diorganotin oxides, (R2SnO)n (R = Me, Et, n-Bu, n-Oct, c-Hex, i -Pr, Ph), with saturated aqueous NH4X (X = F, Cl, Br, I, OAc) in refluxing 1,4-dioxane afforded in high yields dimeric tetraorganodistannoxanes, [R2(X)SnOSn(X)R2]2, and in a few cases diorganotin dihalides or diacetates, R2SnX2. The reported method appears suitable for the synthesis of fluorinated tetraorganodistannoxanes. Identification of [R2(OH)SnOSn(X)R2]2 (R=n-Bu; X = Cl, Br) and [R2(OH)SnOSn(X)R2] [R2(X)SnOSn(X)R2] suggest a serial substitution mechanism starting from [R2(OH)SnOSn(OH)R2]2. X-ray crystal structure determinations are reported for [Me2(AcO)SnOSn(OAc)Me2]2 (29a), [i-Pr2(Br)SnOSn(Br)i-Pr2]2 (20a), [c-Hex2 (F)SnOSn(F)c-Hex2]2 (5a) and [c-Hex2(F)SnOSn(Cl)c-Hex2]2 (36), respectively. These show the presence of a central (R2Sn)2O2 core that is connected, via the oxygen atoms, to R2Sn entities. Acetate (29a) or halides (5a, 20a, 36) complete the coordination about the tin centres.

Reactivity of Sn-phenyl or Sn-naphthyl bond in tetraorganotins, PhnSnNp4-n (Ph = phenyl, Np = α-naphthyl; n = 2,3) towards halogens (Br2 and I2), interhalogens (IBr and ICl), interpseudohalogens (BrCN and ICN) and pseudohalogen (SCN)2 has been studied.It is found that the Sn-Np bond is preferentially cleaved yielding in most cases phenyltin derivatives along with the corresponding α-naphthyl halides.
