Abstract: Reaction of di(p-fluorobenzyl)tin oxide with heteroaromatic carboxylic acid in 1:2 stoichiometry yields compounds of the type (4-F-Bz)2Sn(OOCR)2 [R=3-pyridinyl (1), 4-pyridinyl (2), 2-pyridinyl (3), 2-indolyl (4), 2-furanyl (5), 2-thiophenyl (6), 3-indolyl (7), 3-indolmethyl (8)]. These compounds have been characterized by elemental analysis, IR, 1H and 119Sn NMR spectra. The crystal and molecular structure of compound 1 has been determined by X-ray single crystal diffraction. The results show that the crystal of compound belongs to a monoclinic system with space group P2(1)/c and unit cell dimensions: a=17.634(12) Å, b=12.776(9) Å, c=13.606(9) Å,β=96.991(11)o, Z=4, V=3043(4) Å3, Dc=1.269 Mg/m3, μ=0.904 mm-1, F(000)=1456, R1=0.0405, wR2=0.0682. In compound 1, the tin atom is seven-coordinate in a distorted pentagonal bipyramidal geometry by bridging the pyridine N atom, resulting the one-dimensional infinite chain organotin compound.
