Synthesis and crystal structure of a linear polymeric tributyltin 4-pyridinecarboxylate

Abstract

<span style="mso-bidi-font-size:11.0pt;color:black" lang="EN-IN">The complex tributyltin 4-pyridinecarboxylate has been synthesized by the reaction of tributyltin chloride with sodium 4- pyridinecarboxylate in benzene and characterized by IR, ¹H NMR, elemental analyses, MS and X-ray structural analyses. The crystals are monoclinic, space group P2₁/c, with<i> a=</i>9.6673 (14), <i>b=</i>23.845 (4),<b> </b>c<i>=</i>9.7071 (14)<b> </b>Å;<i> </i>β<i>=</i>112.463 (3)°; <i>V</i>=2067.9(5)<b> </b>ų<b> , </b>Z=4, <i>Dc</i>= 1.324 Mg m^-3, μ=1.242 mm^-1, <i>F</i>(000)=848, <i>R</i>₁=0.0544, <i>WR</i>₂=0.1411. In the crystals, the tin atoms are rendered five- coordinate in a trigonal bipyramidal structure by coordinating with 4-pyridinylearboxlate group. The resulting structure is a linear polymer containing Sn-O and Sn-N bonds whose lengths are 2.170 (5)<b> </b>Å and 2.60 (2)<b> </b>Å, respectively.
