Abstract
A novel seven-coordinate dimer bis[(2,6-pyridinedicarboxylato)(methanol)dibenzyltin(IV)] was synthesized by the reaction of (PhCH2)3SnCl with 2,6-pyridine dicarboxylic acid in 1:1 molar ratio in methanol solution. The structure was characterized by elemental analysis, IR and 1H NMR spectra, and the crystal structure was determined by X-ray single crystal diffraction analysis. The crystal belongs to monoclinic space group P21/n, a =0.96250(19) nm, b = 1.0947(2) nm, c = 1.9965(4) nm, β = 92.31(3)°, Z = 2, V = 2.1019(7) nm3, Dc = 1.574 g/cm3, μ = 1.248 mm−1, F(000)=1000, R1 = 0.0675, wR2 = 0.0836. In the crystals of the complex, each tin atom is seven-coordinated in a distorted bipyramidal structure.
