Sixteen novel β-alkoxycarbonylethyltin trichlorides and the corresponding N-aryl-2-hydroxyacetophenylideneimines complexes have been synthesized and characterized. An Xray crystal structure analysis of the complex of β-methyloxycarbonylethyltin trichloride andN4methylphenyl-2-hydroxyacetophe has been performed. The crystal belongs to space group P 1. The cell parameters are: a=1. 0201 (6) nm, b=1. 082 2(4) nm, c= 1. 394 9(6) nm, a=99. 88(3)°, β=98. 63(4)°, γ=97. 86(4)°, Z=2. The ligands coordinate to tin atom via phenolic oxygen atom. Coordination of carbonyl oxygen atom to tin atomstill exists in the complexes. The coordination number of tin atom is 6.
