The six novel drum organooxotin clusters [PhCH 2Sn(O)(O 2CCH[CDS1]CHAr)] 6 were synthesized by the reaction of 6 were synthesized by the reaction of [(PhCH 2) 3Sn] 2O with ArCHCHCO 2H in 1∶2 molar ratio. The crystal structure of [PhCH 2Sn(O)-(O 2C CH[CDS1]CHPh)] 6 was determined by X-ray single crystal diffraction study. The crystal belongs to triclinic with space group P1 6 was determined by X-ray single crystal diffraction study. The crystal belongs to triclinic with space group P1-, a=1.6771(3) nm, b=1.8020(4) nm, c=2.1073(4) nm, α=108.111(3)°, β=103.614(3)°, γ=104.679(3)°, Z=2, V=5.5033(18) nm 3, D c=1.350 g/cm 3, μ=1.396 mm -1, F(000)=2208, R=0.0606, wR=0.0698. The structure shows a distorted octahedron configuration with six coordination for the central tin atoms.
