| Abstract: | A series of new triorganotin(IV) pyridinedicarboxylates (C2H5)3NH](Me3Sn)3(2,6-pdc)2(H2O)2] (1), (C2H5)3NH](Ph3Sn)3(2,6-pdc)2(H2O)2] (2), (C2H5)3NH]{(PhCH2)3Sn]3(2,6-pdc)2(H2O)2} (3), Me3Sn(3,5-pdc)]n (4), Ph3Sn(3,5-pdc)]n (5), (PhCH2)3Sn(3,5-pdc)]n (6), (Me3Sn)2(2,5-pdc)]n (7), (Ph3Sn)2(2,5-pdc)]n (8) and {(PhCH2)3Sn]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)-H2pdc (pdc = pyridinedicarboxylate) when triethylamine was added. Complexes 1-9 have been characterized by elemental, IR, 1H, 13C and 119Sn 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 Sn?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. |
