|Title:||Synthesis of bis(tri-n-butyltin) esters of dicarboxylic acid and crystal structure of the three-dimensional framework of organotin polymer, bis(tri-n-butyltin) ester of succinic acid|
|Abstract:||Ten bis(tri-n-buyltin) esters of dicarboxylic acid have been synthesized by the reaction of disodium dicarboxylates with the tri-n-butyltin chloride in 1:2 molar ratio and characterized by elemental analysis, IR, and 1H NMR. The crystal structures of bis(tri-n-benyltin) ester of succinic acid (2) have been determined by X-ray single crystal diffraction. The crystal belongs to orthorhombic with space group Pccn, a =20.949(3)Å, b=17.470(3) Å, c=20.345(3) Å, α = 90°, β=90°, γ=90°, V=7445.5(19) Å3, Z=8, Dc=1.242 mg/cm3, μ=1.365 mm-l, F(000)=2864, R1=0.0544, wR2=0.1417. The tin atom is five coordinate in a trigonal bipyramidal structure by bridging two carboxylate groups in different directions. The resulting structure is a three-dimensional framework polymer containing two different tin atom. The framework structure contains large ring directed channels along a, band c-axis.|
