Tris(cyclohexyl)hydroxoantimony(V) compounds, (C6H11)3Sb(OH)Y, Y=Cl, Br, CH3COO, and NO3, were prepared by the hydrolysis of μ-oxo-bis[tris(cyclohexyl)haloantimony(V)], [(C6H11)3SbX]2O, in a mixed solvent of acetone and water(7:3) or by a reaction of silver salts with [(C6H11)3SbX]2O in the same solvent. When Y=Cl and Br, the dehydration of the hydroxo compounds, giving the μ-oxo compounds, [(C6H11)3SbY]2O, occurred readily. However, when Y= CH3COO and NO3, the hydroxo form is stable. In the IR spectra of these hydroxo compounds in dichloromethane solution, the ν(O–H) band was observed at ca. 3630 cm−1 and the ν(Sb–O) band, at 565–513 cm−1. The hydrolysis of several μ-oxo compounds, [R3SbY]2O, R=CH3, C2H5, i-C3H7, C6H5, and p-CH3C6H4, Y=Cl, Br, CH3COO, and NO3, in a water-saturated dichloromethane solution was studied by using the IR spectra. All the compounds were hydolyzed in this solvent, but only the starting μ-oxo compounds were recovered from this solution.
