Abstract: Mono-<i style="">n</i>-butyltin(IV) dichloride complex with the general formula [<i style="">n-</i>BuSnCl<sub>2</sub>(PAP)] has been synthesized by direct reaction of <i style="">n-</i>BuSnCl<sub>3</sub> with pyruvic acid-2-pyridylhydrazone in the presence of KOH in equimolar ratio in absolute methanol under nitrogen atmosphere. Both, the ligand as well as the complex, have been characterized by elemental analyses, UV-visible, IR, <sup>1</sup>H NMR spectral and X-ray diffraction studies. [<i style="">n-</i>BuSnCl<sub>2</sub>(PAP)] is nonelectrolytic in nature. Single crystal X-ray diffraction studies indicate that [<i style="">n-</i>BuSnCl<sub>2</sub>(PAP)], is six-coordinated and adopts a distorted octahedral configuration with the coordination via carboxylic-O, imine-N and pyridyl-N atoms from the ligand. The crystal system of [<i style="">n-</i>BuSnCl<sub>2</sub>(PAP)] is tetragonal with space group I4<sub>1</sub>/<i style="">a</i> and the unit cell dimensions: <i style="">a</i> = 16.602(3)Å, <i style="">b =</i> 16.602(3)Å, <i style="">c</i> = 23.922(8)Å, <i style=""><img src='/image/spc_char/alpha.gif'> </i> = <i style=""><img src='/image/spc_char/beta.gif'></i> = <i style=""><img src='/image/spc_char/gamma2.gif'>=</i> 90˚.
