Thirty -two title complexes ROCOCHR^1CH~2SnCl~3.(2-HOC~6H~4CH= =NC~6H~4-X)(R=Me,Et, n-Bu;R^1=H,Me;X=H,4'-Cl,3'-Br,3'-OH,3',4'-Cl~2,4'- OMe), were synthesized and characterized by elemental analysis, UV-vis, IR,^1H NMR. The crystal structure of n-BuOCOCH~2CH~2SnCl~3.(2- HOC~6H~4CH= =NC~6H~4OMe-4') were determined by the X-ray diffraction analysis. The crystal belongs to monoclinic system, with a=1.4661(3) nm,b=0.9307(2)nm, c=1.7888(4)nm,β=94.04(3)^o;v=2.4348nm^3, D~c=1. 581mg/m^3, z=4,F(000) =1160,μ=1.405mm^-^1,R=0.0354,R~w=0.0486.space group:P2~1/c. The complexes exist as a discrete monomer. The tin atom has a distorted octahedral geometry due to intramolecular coordination of the carbonyl oxygen and the phenolic oxygen of the Schiff base ligands. The coordination number of tin atom is 6.
