Five new dicarboxylate organotin complexes under hydrothermal condition: Syntheses, characterization and crystal structures of 1D, 2D and 3D polymers constructed from dimeric tetraorganodistannoxane units

Five new diorganotin(IV) complexes of the types {(Me2Sn)2[μ4-(C8H3NO6)](μ3-O)}n (1), {(Me2Sn)2[μ3-(C8H8O4)](μ3-O)}n (2), {(Me2Sn)2[μ4-(C8H10O4)](μ3-O)}n (3) {(Me2Sn)2[μ4-(C8H10O4)](μ3-O)}n (4) and {(Me2Sn)2[μ4-(C10H14O4)](μ3-O)}n (5) have been synthesized by reactions of 5-nitroisophthalic acid, meso-cis-4-cyclohexene-1,2-dicarboxylic, meso-cis-1,4-cyclohexanedicarboxylic acid, meso-cis-1,3-cyclohexanedicarboxylic acid and chiral cis-(1R,3S)-(+)-camphoric acid with trimethyltin chloride under hydrothermal condition. All complexes were characterized by elemental analysis, IR, 1H NMR, 13C NMR, 119Sn NMR and X-ray crystallography. The structural analyses show that complex 1 has a 1D infinite polymeric chain in which 5-nitroisophthalic acid acts as a tetradentate ligand coordinating to dimethyltin(IV) ions, complexes 2, 3 and 4 possess 2D polymeric structures in which dicarboxylate acid act as tridentate or tetradentate ligands coordinating to dimethyltin(IV) ions, complex 5 possesses a irregular 3D framework in which chiral cis-(1R,3S)-(+)-camphoric acid acts as a tetradentate ligand coordinating to dimethyltin(IV) ions.

Five new diorganotin(IV) complexes have been synthesized under hydrothermal condition. All complexes were characterized by elemental analysis, IR, 1H NMR, 13C NMR, 119Sn NMR, TGA and X-ray crystallography. The X-ray crystallography shows that all of the complexes possess 1D, 2D and 3D polymers constructed from dimeric tetraorganodistannoxane units.Figure optionsDownload as PowerPoint slide
