| Abstract: The Di(o-fluorobenzyl)tin Bis(2-picolinate) (1) and the one-dimensional chain tri(o-fluorobenzyl)tin 4-picolinate (2) have been synthesized. The crystal structures of the complexes were determined by X-ray diffraction.The crystal 1 belongs to Tetragonal space group I41/a with a=1.562 0(3) nm, b=1.562 0(3) nm, c=1.984 7(4) nm, α=β=γ=90°, V=4.842 4(16) nm3, Z=8, Dc=1.594 Mg·m-3, μ(Mo Kα)=11.06 cm-1, F(000)=2 320, R1=0.024 3, wR=0.062 5. The crystal 2 belongs to Monoclinic space group P21/n with a=0.869 8(3) nm, b=1.880 5(7) nm, c=1.475 1(5) nm, β=90.937(6)°, V=2.412 3(15) nm3, Z=4, Dc=1.564 Mg·m-3, μ(Mo Kα)=11.07 cm-1, F(000)=1 136, R1=0.028 8, wR2=0.057 9. The crystal 1 is monomeric,with six-coordinated tin atom in a distorted octahedron geometry. In the crystal 2, the tin atom rendered five-coordinate in trigonal bipyramid structure by bridging pyridine N atom,resulting the one-dimensional chain polymer.
