Self-assembly of triorganotin(IV) moieties with 2,3,4,5-tetrafluorobenzoic acid and 4,4′-bipy, triphenylphosphine oxide or phen: Syntheses, characterizations and supramolecular structures

Abstract: A series of triorganotin (IV) complexes with 2,3,4,5-tetrafluorobenzoic acid and mixed-ligands of the types: R3Sn(O2CC6HF4) m ·L (m =1, L=0, R=Ph 1; m =1, L=Ph3PO, R=Ph 4, Me 5), [R3Sn(O2CC6HF4)] m ·L (m =2, L=4,4′-bipy, R=Ph 2, Me 3; m = n, L=0, R=Me 6), and [R3Sn(O2CC6HF4)·(H2O)] m ·L·C2H5OH (m =2, L=Phen, R=Ph 7, Me 8), (4,4′-bipy=4,4′-bipyridyl; Phen=1,10-phenanthroline), have been synthesized by the reaction of triorganotin chloride and 2,3,4,5-tetrafluorobenzoic acid in the presence of mixed-ligands: 4,4′-bipy, triphenylphosphine oxide, or phen. All complexes were characterized by elemental analysis, IR, 1H, 13C, 119Sn NMR spectroscopy analysis. Except for 5 and 8, all the complexes were also characterized by X-ray crystallography.
