Nine title compounds were synthesized from 2- (ethylenedioxythlene) methylene-3-carbonyl-5-aryl-4-pentenoic acid with triphenyltin hydroxide. X The crystal structure of 3b is determined by the ray diffraction method. The crystal belongs to the triclinic system with space group Pl, α = 0.9074 (2) nm, b = 1.6809 (3) nm, c = 2.1834 (4) nm and α = 77.57 3) °, β = 88.04 (3) °, γ = 89.47 (3) °, V = 3.2503 nm ~ 3, Z = 2 and R = 0.0592. Bidentate ligand and tin atoms form an intramolecular pentacoordination structure.
