Syntheses and Characterization of 2D and 3D Organotin Polymers with Phenylsuccinic Acid and Trimethyltin Chloride Under Different Conditions

Two types of di- and trimethyltin(IV) polymers [(Me2Sn)4O2(C10H8O4)4]n1 and [(Me3Sn)2(C10H8O4)]n·DMF 2 have been synthesized by the reaction of trimethyltin chloride with (±)-phenylsuccinic acid under two different experimental conditions. Both of the complexes are characterized by elemental analysis, IR, NMR (1H, 13C, 119Sn) spectroscopy and X-ray crystallographic diffraction analysis. The structural analyses show that complex 1 is a two-dimensional corrugated sheet polymer consisting of dimeric tetraorganodistannoxane units and bridging ligands. Complex 2 is a 3D corrugated polymer in which the deprotoned acid occurs as a tetradentate ligand and is bonded by the four oxygen atoms. It is worth noting that the X-ray diffraction study reveals that complex 2 crystallizes in the orthorhombic space group P212121, which is chiral space group.
