The reaction of pentaphenylantimony and the oxime HON=CRR′ taken in 1:1 molar ratio in toluene gave tetraphenylantimony oximates Ph 4SbON=CRR′ (CRR′ = C6H9-C 6H9-2 (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)° in I and 176.58(6)° in II. The Sb-C bond lengths lie in the ranges of 2.120(4)-2.203(4) for I and 2.122(2)-2.181(2) for II. The Sb-O bond lengths are 2.120(2) (I) and 2.166(1) (II). The lengths of the intramolecular Sb···N contacts are 2.806(3) and 2.918(2) in I and II, respectively.
