Abstract

A series of hetero- and homoleptic organoamidoantimony(iii) complexes of the type [SbLMe3−nCln] (n = 2, 1, 0) (HLMe = p-HC6F4NH(CH2)2NMe2) incorporating a bulky amido fluorinated ligand tethered with an amino pendant arm, have been successfully synthesised and fully characterised as monomers in the solid state. [Sb(p-HC6F4NC2H4NMe2)Cl2] (1), [Sb(p-HC6F4NC2H4NMe2)2Cl] (2), and [Sb(p-HC6F4NC2H4NMe2)3] (3) were isolated by metathesis reactions involving different stoichiometric ratios between SbCl3 and Li(p-HC6F4N(CH2)2NMe2) (LiLMe) in non-coordinating solvents, while [Sb(p-HC6F4NC2H4NMe2)Cl2] (1) was also synthesised by the direct reaction between SbCl3 and HLMe in THF providing an interesting alternative pathway to access these types of compounds.
