Abstract

The structure of the tetra(p-tolyl)antimony compounds p-Tol₄SbX (X = Br (1), OC(O)Ph ∙ PhH (2), OSO₂C₆Me₃-2,4,6 (3)) is determined by X-ray diffraction analysis (XRD). According to the XRD data, the antimony atoms in complexes 1–3 exhibit a distorted trigonal bipyramidal coordination with three aryl ligands in the equatorial plane, and the axial angles CSbX are 174.75(8)°, 175.13(9)°, and 174.51(6)°, respectively.
