Syntheses and structures of tris(para-tolyl)-, tris(3-fluorophenyl)-, and tris(4-fluorophenyl)antimony dioximates

Tris( para -tolyl)antimony bis(2-oxybenzaldoximate) ( I ), tris( para -tolyl)antimony bis(2-nitrobenzaldoximate) ( II ), tris( para -tolyl)antimony bis(2-bromobenzaldoximate) ( III ), tris(3-fluorophenyl)antimony bis(2-oxybenzaldoximate) ( IV ), tris(4-fluorophenyl)antimony bis(2-bromobenzaldoximate) ( V ), and tris(4-fluorophenyl)antimony bis(2-nitrobenzaldoximate) ( VI ) are synthesized by the reactions of tris( para tolyl)-, tris(3-fluorophenyl)-, and tris(4-fluorophenyl)antimony with 2-oxy-, 2-nitro-, and 2-bromobenzaldoxime in diethyl ether in the presence of tert -butyl hydroperoxide. The Sb atoms in complexes I – VI have a distorted trigonal bipyramidal coordination mode with the oximate ligands in the axial positions.
