The one-dimensional chain tfi (o-chlombenzyl) tin 4-picohnate has been synthesized. The crystal structure of the complex was determined by X-ray diffraction. The crystal belongs to monoclinic with space group P2(1) / n with a=0.8844 (3) nm, b=1.8931(6) nm, c =1.5387 (5) nm^3=92.266(5)°, V=2.5741(14) nm^3, Z=4, Dx=1.593Mg·m^-3,μ(MoKa)=13.29cm^-1 ,F(000)=1232, R1=0.0377, wR2=0.0936. In the crystal, the tin rendered five-coordium in trigonal bipyramidal structure hy bridging pyridine N atom, resu...
