【Abstract】 Organotin(Ⅳ) compound {[(n-C4H9)2Sn(0.5·O2CC12H10N)(0.5·CH3O)]2O}2 was synthesized by the reaction of n-dibutyltin oxide with N-phenylanthranilic acid.The compound was characterized by elemental analysis,IR and 1H NMR analyses.The crystal structure was determined by X-ray single crystal diffraction method.The result indicates that crystal belongs to triclinic,space group P-1 with a =1.173(2) nm,b = 1.256(2) nm,c= 1.329(2) nm,α = 82.29(3)°,β = 71.83(3)°,γ = 65.36(3)°,V = 1.690(5) nm3,Z = 1,μ= 1.509 mm-1,Dc = 1.425 Mg·m-3,F(000) =736,R = 0.056 9,wR = 0.158 9,GOF = 1.074.The complex is a centrosymmetric structure mode with a four-member central endo-cyclic Sn2O2 unit in which two bridged oxygen atoms both connect with an exo-cyclic tin atom.The endo-cyclic tin atoms and the exo-cyclic tin atoms are all five-coordination and have coordination geometry of distorted trigonal bipyramid.更多还原
