  Synthesis and Structure of Tetraphenylantimony Oximates Ph₄SbON=CRR  (CRR′ = C₆H₉–C₆H₉-2 and R = Ph, R′ = C(O)Ph)

  摘要：

  The reaction of pentaphenylantimony and the oxime HON=CRR' taken in 1:1 molar ratio in toluene gave tetraphenylantimony oximates Ph4SbON=CRR' (CRR' = C6H9-C6H9-2 (I) and R = Ph, R'= C(O)Ph (II)). According to X-ray diffraction data, the Sb atoms in I and II have a distorted trigonal-bipyramidal coordination with oximate ligands in the axial positions. The CaxSbO angles are 177.6(1)degrees in I and 176.58(6)degrees in II. The Sb-C bond lengths lie in the ranges of 2.120(4)-2.203(4) Angstrom for I and 2.122(2)-2.181(2) Angstrom for II. The Sb-O bond lengths are 2.120(2) Angstrom (I) and 2.166(1) Angstrom (II). The lengths of the intramolecular (SbN)-N-... contacts are 2.806(3) and 2.918(2) Angstrom in I and II, respectively.
