  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.

  A number of quadruply and triply bridged organodiantimony(V) compounds have been synthesized by reactions of [(SbR 2 BrO) 2 ] (R = Ph or p-tolyl) and [(SbR 3 X) 2 O] (R = Ph or p-tolyl, X = Br or Cl) with Na(O 2 AsMe 2 ), Na(O 2 AsPh 2 ) or Na(O 2 AsMe 2 ). The compounds have been characterised by a range of spectroscopic methods and crystal structures are reported for two quadruply bridged, [(SbPh 2 ) 2 (µ-O) 2 (µ -O 2 AsMe 2 ) 2 ] and [Sb(p-MeC 6 H 4 ) 2 } 2 (µ-O) 2 (µ-O 2 AsMe 2 ) 2 ], and four triply bridged compounds, [(SbPh 3 ) 2 (µ-O)(µ-O 2 PMe 2 ) 2 ], [(SbPh 3 ) 2 (µ-O)(µ-O 2 AsMe 2 ) 2 ], [(SbPh 3 ) 2 (µ-O)(µ-O 2 AsPh 2 ) 2 ] and [Sb(p-MeC 6 H 4 ) 3 } 2 (µ-O)(µ-O 2 PMe 2 ) 2 ]. Related trimethylantimony(V) compounds, i.e. [SbMe 3 (O 2 PMe 2 )} 2 O] and [SbMe 3 (O 2 AsPh 2 )} 2 O], which are highly moisture sensitive, have also been obtained.

  通过[(SbR₂BrO)₂] (R = Ph 或 p-tolyl) 和 [(SbR₃X)₂O] (R = Ph 或 p-tolyl, X = Br 或 Cl) 与 Na(O₂AsMe₂)、Na(O₂AsPh₂) 或 Na(O₂AsMe₂) 的反应，合成了多种四重和三重桥连的组织二锑(V)化合物。这些化合物通过一系列光谱方法进行了表征，并报道了两种四重桥连化合物 [(SbPh₂)₂(µ-O)₂(µ-O₂AsMe₂)₂] 和 [Sb(p-MeC₆H₄)₂}₂(µ-O)₂(µ-O₂AsMe₂)₂]，以及四种三重桥连化合物 [(SbPh₃)₂(µ-O)(µ-O₂PMe₂)₂]、[(SbPh₃)₂(µ-O)(µ-O₂AsMe₂)₂]、[(SbPh₃)₂(µ-O)(µ-O₂AsPh₂)₂] 和 [Sb(p-MeC₆H₄)₃}₂(µ-O)(µ-O₂PMe₂)₂] 的晶体结构。还获得了高度吸湿性的相关三甲基锑(V)化合物，即 [SbMe₃(O₂PMe₂)}₂O] 和 [SbMe₃(O₂AsPh₂)}₂O]。
