Synthesis, structure, and reactions of tris(4-fluorophenyl)antimony dibromide

Abstract

The interaction of tris(4-fluorophenyl)antimony with copper(II) bromide in acetone has afforded tris(4-fluorophenyl)antimony dibromide; recrystallization of the product from ethanol has yielded the (4-FC₆H₄)₃SbBr₂·[(4-FC₆H₄)₃SbBr]₂O adduct. [(4-FC₆H₄)₃SbCNS]₂O oxide has been prepared from tris(4-fluorophenyl)antimony dibromide and potassium thiocyanate in aqueous-acetone solution. Antimony atoms in the molecules of the prepared compounds exhibited the distorted trigonal bipyramid coordination with the electron-accepting ligands in the axial positions.
