The identification of some new antimony(III) compounds containing fluoroxyl ligands by 19F solution-state NMR spectroscopy: crystal and molecular structure of Ar′Ar2″Sb (Ar′ = 2,6-(CF3)2C6H3; Ar″ = 2,4-(CF3)2C6H3)

Some new antimony(III) derivatives with 2,6-(CF3)2C6H3 (Ar′) and/or 2,4-(CF3)2C6H3 (Ar″) ligands have been identified in solution by 19F NMR spectroscopy. The compound Ar′Ar2″Sb has been characterised by single-crystal X-ray diffraction at 120 K.
