【Abstract】 Bis (tribenyltin)ester of glutaric acid were synthesixed by the reaction of sodium of glu-taric acid with the tribenyltin chloride in 1:2 molar ratio and were characterixed by IR.1H NMR and MS. The crystal structures was determined by X-ray single crystal diffraction. The crystal belongs to or-thorhombic with space group C2221,a = 1. 507 5(5)nm,b=4. 802(17) nm,c = 2. 8944(9) nm,α=90 ,β= 90 ,v=90 ,V=20. 953(12) nm3,Z=8,Dc = 1. 316 g/cm3,μ=1. 266 mm-1,F(000) = 8 280,R1 = 0. 054 6, wR2 = 0. 1182. The tin atom rendered five-coordinate in a trigonal bipyramidal structure by bridging two carboxylate groups in different direction and the resulting structure is three-dimensional framework polymer containing five different tin atom.更多还原
