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

摘要

Five new diorganotin(IV) complexes of the types {(Me2Sn)(2)[mu(4)-(C8H3NO6)](mu(3)-O)}(n) (1), {(Me2Sn)(2)[mu(3)-(C8H8O4)](mu(3)-O)}(n) (2), {(Me2Sn)(2)[mu(4)-(C8H10O4)](mu(3)-O)}(n) (3) {(Me2Sn)(2)[mu(4)-(C8H10O4)](mu(3)-O)}(n) (4) and {(Me2Sn)(2)[mu(4)-(C10H14O4)](mu(3)-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-cyclo-hexanedicarboxylic acid and chiral cis-(1R,3S)-(+)-camphoric acid with trimethyltin chloride under hydrothermal condition. All complexes were characterized by elemental analysis, IR, H-1 NMR, C-13 NMR, Sn-119 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. 2008 Elsevier Ltd.
