Five (n Bu) 2 Sn (O2 CCHCHAr)] 2 O} 2 dimethyldibutyltin aryl acrylate oxides were synthesized by the reaction of (n Bu) 2 SnO and ArCHCHCO2 H. The results of elemental analysis, The structure of {[(n Bu) 2 Sn (O2 CCHCHPh)] 2 O} 2 (1) was determined by X-ray single crystal diffraction and the results showed that compound 1 was synthesized by Sn2 O2 tetrahedron centered symmetrical dimer structure, the inner ring tin is a five-coordinate distorted triangular double-cone configuration, and the outer ring tin is a six-coordinated distorted plus cap triangular double cone structure. The compound Is a triclinic system with space group P1-, a = 1 0 172 (11) nm, b = 1 3 80 4 (16) nm, c = 1 470 3 (17) nm, α = 10 6 75 0 , Β = 10 5 61 (2)) °, γ = 10 0 2 95 (18) °, Z = 1, V = 1 82 9 (4) nm -3, Dc = 1 413 g / 1 40 0 mm-1, F (0 0 0) = 792, R = 0 0 5 5 9, wR = 0 12 5 0.
