| Abstract: | The compound was synthesized by the reactions of di-n-butyl tin oxide and 2-benzoylbenzoic acid with azeotropic removal of water in the solvents of benzene.The compound was characterized by elemental analysis,1H NMR, FT-IR spectroscopy and single crystal X-ray diffraction analysis.The crystal structure reveals that all tin ions are pent-coordinated with distorted trigonal-bipyramidal geometries.The central Sn2O2 square unit is linked to two external tin ions via bidentate carboxylate ligands and oxygen atoms,exhibiting three distannoxane rings.The geometries of two external tin ions are further completed by two mono-dentate carboxylate ligands.The tin atom geometries are similar and are based on a trigonal bipyramidal arrangement.The antibacterial activity of compound was preliminary studied. |
