A series of new mono-and pentafluorophenylantimony(III and V) arylcarboxylates of the type ArnSb(OOCC6H4OCH3-2)3-n and Ar3Sb(OOCC6H4OCH3-2)2 (Ar = p-FC6H4-, m-FC6H4-and C6F5-, n =1 or 2) have been synthesized by the reaction of fluorophenylantimony (III or V) chlorides and the sodium salt of 2-methoxybenzoic acid in the presence of 15-crown-5 as phase transfer catalyst. A representative compound, namely trimethylantimony(V) bis(2-methoxybenzoate) has also been synthesized for the sake of spectral comparisons. The van't Hoff factor 'i' and molar conductance data of the compounds revealed them to be monomeric and non-conducting in nature. The compounds were characterised by the usual physicochemical techniques e.g., elemental analyses, UV, IR and NMR (1H, 13C and 19F). Compound (III-VIII) are tentatively assigned as a trigonal bipyramidal structure in which the 2-methoxybenzoate acted as monodentate ligand.
