Specifics of reaction between tri-ortho-tolylantimony and cyclohexanone oxime in the presence of peroxides: Structure of tri-ortho-tolylantimony bis(cyclohexanone oximate) and its adduct with tri-ortho-tolylantimony oxide

摘要

Tri-ortho-tolylantimony bis(cyclohexanone oximate) (o-Tol)(3)Sb(ON=C6H10-cyclo)(2) (I) has been synthesized by the reaction between tri-o-tolylantimony and cyclohexanone oxime in the presence of tert-butyl hydroperoxide (1: 2: 1 mol/mol/mol). When the molar ratio of reagents was 1: 1: 1, the adduct (o-Tol)(3)Sb(ON=C6H10-cyclo)(2) center dot [(o-Tol)(3)SbO](2) (II) has been isolated from the reaction. According to X-ray diffraction data, the axial OSbO and equatorial CSbC angles in complex I are 168.61(7)A degrees and 112.4(1)A degrees-124.2(1)A degrees, respectively. The Sb-C and Sb-O bonds are 2.123(3)-2.126(2) and 2.062(2), 2.068(2) , respectively. The molecules in adduct II have geometric parameters close to the respective parameters of the individually crystallizing compounds.
