摘要

A series of new triorganotin(IV) pyridinedicarboxylates [(C2H5)(3)NH][(Me3Sn)(3)(2,6-pdc)(2)(H2O2)(2)] (1), [(C2H5)(3)NH][(Ph3Sn)(3)(2,6- pdc)(2)(H2O)(2)](2), [(C2H5)(3)NH]{[(PhCH2)(3)Sn](3)(2,6-pdc)(2)(H2O)(2)} (3), [Me3Sn(3,5-pdc)](n) (4), [Ph3Sn(3.5-pdc)](n) (5), [(PhCH2)(3)Sn(3,5-pdc)](n) (6), [(Me3Sn)(2)(2,5-pdc)] (7), [(Ph3Sn)(2)(2,5-pdc)](n) (8) and {[(PhCH2)(3)Sn](2)(2,5-pdc)}(n) (9) were synthesized by the reaction of trimethyltin(IV), triphenyltin(IV) or tribenzyltin(IV) chloride with 2,6(3,5 or 2,5)-H(2)pdc (pdc = pyridinedicarboxylate) when triethylamine was added. Complexes 1-9 have been characterized by elemental, IR, H-1, C-13 and Sn-119 NMR analyses. Among them complexes 1, 5 and 7 have also been characterized by X-ray crystallographic diffraction analyses. Complex 1 has a trinuclear structure and forms a 2D supramolecular structure due to the coordinated water molecules via hydrogen bonds to the pendant O atoms of the carboxyl groups and the N atoms derived of the pyridine ring. Complex 5 forms a 1D polymeric chain by the intermolecular (SnN)-N-... (N atom derived of pyridine ring) interactions. Complex 7 has a network structure where 2,5-pyridinedicarboxylate acts as a tetradentate ligand coordinated to trimethyltin(IV) ions. (c) 2005 Elsevier B.V. All rights reserved.
