The five organotin compounds {[(n-Bu)2Sn (O2CCHCHAr)]2O}2 were synthesized by the reaction of (n-Bu)2SnO with ArCHCHCO2H in 1∶1 molar ratio. The crystal structure of {[(n-Bu)2Sn(O2CCHCHPh)]2O}2 was determined by X-ray single crystal diffraction. This compound belongs to centrosymmetric dimer structure mode with a four-membered central endo-cyclic Sn2O2 unit in which the bridged oxygen atoms are tri-coordinated. Each bridged oxygen atom also connects with an exo-cyclic tin atom. The endo-cyclic tin atoms are five-coordinated and have coordination geometry of distorted trigonal bipyramid. The exo-cyclic tin atoms are six-coordinated and have coordination geometry of capped trigonal bipyramid with very similarly distorted mode. The crystal belongs totriclinic with space group P1-, a=1.0172(11) nm, b=1.3804(16) nm, c=1.4703(17) nm, α=106.750(18)°, β=105.61(2)°, γ=100.295(18)°, Z=1, V=1.829(4) nm-3, Dc=1.413 g/m3, μ=1.400 mm-1, F(000)=792, R=0.0559, wR=0.1250.

Key words: organotin compound, aromatic substituted acrylic acid, synthesis, crystal structure
