Abstract
The six organotin complexes dibutyltin(IV) bis(heteroaromatic carboxylate) were synthesized by the reaction of (n-Bu)2SnO with heteroaromatic carboxylic acid in 1:2 molar ratio. These complexes have been characterized by elemental analysis, IR, 1H, 13C and 119Sn NMR. The crystal structure of dibutyltin(IV) bis(2-thiazolylcarboxylate) was determined by X-ray single crystal diffraction. This compound is a weakly bridged dimer through weak interaction Sn···O between molecules. The tin atoms took six-coordinate skew-trapezoidal bipyramidal geometry. The crystal of complex 3 belongs to monoclinic symmetry with space group P21/c, a=1.863(2) nm, b=2.220(3) nm, c=1.0395(10) nm, β=90.275(16)°, Z=8, V=4.292(8) nm3, Dc=1.514 Mg/m3, μ=1.406 mm-1, F(000)=1968, S=0.999, R=0.0549, wR=0.1011.
