Three novel Schiff base adducts [SnMe2Cl2(Hcdacacen)] (1), [SnBu2Cl2(Hcdacacen)2] (2) and [SnPh2Cl2(Hcdacacen)2] (3) have been synthesized by reaction of SnR2Cl2 (R = Me, Bu and Ph) with a new Schiff base ligand methyl-2-[2-(acetylacetoneimino)ethylamino]-1-cyclopentene-1-dithiocarboxylate (Hcdacacen). The ligand and complexes were characterized by elemental analysis and spectroscopic studies. Spectroscopic data suggest that Hcdacacen exists predominately in ketamine tautomeric form and in all complexes acts as a monodentate neutral ligand coordinates to the metal through oxygen atom, while the sulfur atom and imine nitrogen is not involved in the coordination to the tin.
