Synthesis and structure of bis(2,4,6-tribromophenoxy)triphenylantimony
Bis(2,4,6-tribromophenoxy)triphenylantimony was synthesized by reacting triphenylstibine with 2,4,6-tribromophenol in ether in the presence of hydrogen peroxide. Its structure was determined by X-ray diffraction analysis. The coordination polyhedron of the Sb atom is a distorted trigonal bipyramid with the aroxy groups in the axial positions. The bond lengths are Sb(1)-C(Ph) 2.095(4)-2.106(4) A and Sb(1)-O(1,2) 2.099(3) and 2.092(3) A. The value of the O(1)SbO(2) axial angle is 177.3(1)°.
