Structural featuresof µ-oxo-bis(triarylaroxyantimony): [Ar3Sb(OAr’)]2O, Ar = Ph, Ar’ = C6H2Cl3-2,4,6, C6H2Br2-2,6-(t-Bu)-4; Ar = p-Tol, Ar’ = C6H2(NO2)3-2,4,6

Triphenylantimony reacting with 2,4,6-trichlorophenol, 2,6-dibromo-4-tert-butylphenol and 2,4,6-trinitrophenol in the presence of tert-butylhydroperoxide in water-ether solution forms µ-oxo-bis[triphenyl(2,4,6-trichlorophenoxy)antimony] (1), µ-oxo-bis[triphenyl(2,6-dibromo-4-tert-butylphenoxo)аntimony] (2), µ-oxo-bis[tri-p-tolyl(2,4,6-trinitrophenoxo)antimony] (3) with high yield. The 1,2,3 angles SbOSb equal 143.6(2)°, 143.66(16)°, 143.2(2)°. Antimony atoms have distorted trigonal-bipyramidal coordination. Bonds of the antimony atom to the bridging oxygen atom [1.968(4), 1.973(4) Å (1), 1.971(3), 1.979(3) Å (2), 1.946(4), 1.971(3) Å (3)] are shorter than those to the oxygen atoms of aroxy groups [2.111(5), 2.180(3) Å (1), 2.140(3), 2.160(3) Å (2), 2.246(4), 2.364(3) Å (3)].
