Abstract
Oxidation of pentaphenylantimony with atmospheric oxygen in toluene on heating gives μ-oxo-bis(tetraphenylantimony) (yield 63%). Its reaction with tetrafluorophthalic anhydride gives bis(tetraphenylantimony) tetrafluorophthalate (yield 94%). According to single-crystal X-ray diffraction data, the antimony atoms in the molecule of bis(tetraphenylantimony) tetrafluorophthalate have a distorted trigonal bipyramidal coordination with the following geometries: Sb-O bond lengths 2.357(3) and 2.283(3) Å, Sb-C bond lengths 2.108(4)-2.141(4) and 2.100(5)-2.158(4) Å, and CSbO angles 177.42(14)° and 176.18(14)°.
