  Oxygen bridged hexa(organo)di-antimony compounds: Hydrolysis by traces of moisture and crystal structures of [SbR3Br]2O, where R = p- or o-tolyl

  摘要：

  H-1 and C-13 NMR spectroscopy of four compounds of the type [SbR3X](2)O, where X = Br and R = Ph, p-tolyl and o-tolyl or X = Cl and R = Me, have been interpreted as showing that unless stringent precautions are taken to exclude moisture there is cleavage of the oxygen bridge to give solutions which contain both the hydroxo species, SbR3(OH)X, and the original bridged compound. This is in agreement with earlier results from IR spectra of compounds of this type in the presence of water. Rigorous exclusion of moisture leads to NMR spectra of only the unhydrolysed compound and this is the only product isolated when NMR solutions showing the presence of both compounds are crystallised. On the other hand, a stable hydroxobromide, Sb(mesityl)(3)Br(OH), has been isolated from hydrolysis of Sb(mesityl)(3)Br-2. Crystal structures are reported for the o- and p-tolyl isomers of [Sb(tolyl)(3)Br](2)O; the latter has crystallographically imposed 3 symmetry with a linear Sb-O-Sb bridge but the two independent molecules of the o-tolyl derivative have bridge angles of 161.0(2) and 171.5(2)degrees, respectively.
