Abstract: Organotin(Ⅳ) compound {[(nC4H9)2Sn(05·O2CC12H10N)(05·CH3O)]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) nm3, 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 Sn2O2 unit in which two bridged oxygen atoms both connect with an exocyclic 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.
