Synthesis and structure of tris(4-fluorophenyl)antimony dicarboxylates

Аннотация

The interaction of tris(4-fluorophenyl)antimony with chloroacetic, 4-nitrophenylacetic, and benzoic acids in diethyl ether in the presence of tert-butyl hydroperoxide has yielded tris(4-fluorophenyl)antimony dicarboxylates, their Sb atoms bearing distorted trigonal bipyramid coordination with the carboxylate ligands in the axial positions. The intramolecular contacts between Sb atom and carbonyl O atom are formed in the molecules of the products. Their crystal packing is determined by weak intermolecular hydrogen bonds of the H···F and H···O=C types.
