摘要：

A series of organotin(IV) derivatives were obtained employing 2,6-pyridinedicarboxylate as ligand: [{SnBu3(OOC)(2)C5H3N}(n)] (1), [SnBuCl(OOC)(2)C5H3N] (2) and [Sn(CHCH2)(2)(OOC)(2)C5H3N] (3). They were fully characterised by multinuclear NMR [H-1, C-13{H-1}, and Sn-119{H-1}], IR spectroscopies and elemental analysis. In addition suitable crystals of (3) have shown a dimmeric arrangement by X-ray crystallographic studies, held together by Sn-O intermolecular interactions which persists in solution. The crystal packing shows hydrogen bonds joining the dimmers, forming two infinite one-dimensional chain. Each monomer comprises a Sn(IV) centre bonded to a pyridinecarboxylate-containing ring, through both nitrogen and oxygen donor atoms. It is also co-ordinated by a water molecule and two vinyl groups.
