The triorganoantimony oxides prepared by oxidation of R3Sb (R=4-ClC6H4, 4-FC6H4, 2-CH3OC6H4, 2,5-(CH3)2C6H3) and of 9-phenyl-9-stibafluoren, (C6H5)(2,2'-C6H4C6H4)Sb, with H2O2 in acetone, shown by IR data to be dimeric in the solid state, and a structure with a four-membered Sb-O-Sb-O ring is proposed.The analogous oxidation of tris(2,4,6-trimethylphenyl)antimony produced a dihydroxide, the structure of which has been determined by X-ray diffraction.In this compound Sb has only a slightly distorted trigonal bipyramidal environment with OH groups in apical positions.The Sb-O(H) bond distance of 202.7(3) pm is in the normal range of covalent SbO bond distances.Intermolecular hydrogen bonding is excluded by the IR and diffraction data.
