THE PREPARATION AND TIN-119 MOESSBAUER SPECTRA OF ANIONIC ORGANOPENTAHALOGENO- AND TETRAHALOGENO-STANNATE(IV) COMPLEXES

, p. 59 - 67 (1981)
A series of anionic monoorgano-pentahalogenostannate(IV) complexes, M2+2-, where M = K+, Me4N+, Et4N+ or MePPh3+; X = F, Cl or Br; R = Bu, Ph or R'OCOCH2CH2 (R' = Me or Et), has been prepared and these compounds have been studied by 119mSn Moessbauer spectroscopy.The novel mono-organo-tetrachlorostannate salts, Me4N+-, where R' = Et, R, i-Pr or Bu, have been synthesised and their infrared spectra indicate that the carbonyl group is coordinated to tin, thereby completing an octahedral configuration about the metal.When R' = Et, the pentachlorostannate salt, (Me4N)2+2-, containing a free carbonyl group, could also be isolated, whilst with the weaker electron donating methyl group, only the pentachlorostannate complex was formed.
