  摘要：

  Hydrolysis of triphenylantimony dibromide or tri(o-tolyl)antimony dibromide in benzene yields the solvates (Ph3SbBr)(2)O center dot 2PhH (triclinic modification) (I) and [(2-MeC6H4)(3)SbBr](2)O center dot 0.5PhH (II), in which the Sb atoms have a distorted trigonal-bipyramidal coordination. The aryl ligands are in the equatorial positions; the bridging oxygen atom and the terminal Br ligands occupy the axial positions. The bond lengths in I: Sb-C, 2.103(2)-2.125(2) , Sb-O, 1.976(1) and 1.979(1); and Sb-Br, 2.7128(2) and 2.7592(2) . The bond lengths in II (): Sb-C, 2.109(6)-2.145(3) ; Sb-O, 1.954(4)-1.958(4) ; and Sb-Br, 2.7355(8)-2.7624(7) . The angles SbOSb are equal to 138.83(6)A degrees in I and 170.8(3)A degrees and 161.6A degrees in II.

  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.

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

  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.

• Reactions of [SbR3X2]2O with carboxylates and the crystal structures of [SbPh3(O2CCF3)2]2O and [SbMe3(O2CCH3)2]2O

  日期：1998.3

  Reactions of [SbPh3Br](2)O and [SbMe3Cl](2)O with a number of carboxylates lead to halogen substitution and formation of either [SbR3(O2CR')](2)O or SbR3(O2CR')(2). X-ray structures for two of the products, [SbPh3(O2CCF3)](2)O and [SbMe3(O2CCH3)](2)O, show that the carboxylates are unidentate. From NMR spectroscopy, the oxygen bridged compounds are hydrolysed by adventitious water giving SbR3(O2CR')OH in solution but when R = phenyl the original compounds can be recovered on crystallisation.
