Neutral Adducts of Tri Arylantimony Mixed Halides with Oxygen, Nitrogen and Sulphur Donors

Abstract

A series of molecular adducts of (p-FC6H4)3SbCl2 and (p-FC6H4)3SbIX (X = Cl, Br) with Lewis bases having oxygen, nitrogen and sulphur donor have been synthesized. The complexes isolated as solid compounds were characterized by elemental analysis, molar conductance, IR and 1H and 19F NMR spectroscopy. Elemental analysis, molar conductance and molcular weight data have been used to the proposed formulation of the complexes. The observed values of molecular weight indicate their monomeric constitution. While the values of molar conductance shows the absence of ionic species in the solution. IR- and NMR spectra reflected octahedral structure of these neutral adducts in which three R groups (R = p-FC6H4, p-ClC6H4) and one L (L = DMSO, DMF, Py, Ph3PO, TU) occupied the equatorial positions with trans IX groups at axial positions.
