SnI with 2,6-pyridinedicarboxylic acid, respectively in the presence of sodium methoxide or potassium iso-propoxide. The prepared compounds were characterized by mass spectrometry, IR, 1 H, 13 C and 119 Sn NMR spectroscopies. The molecular structures of both complexes were determined by a single-crystal X-ray analysis. The X-ray structure revealed pentagonal bipyramidal geometry around the tin atom for compound 1, which is incorporated with a hexacoordinated monosodium derivative of 2,6-pyridinedicarboxylic acid. Complex 2 adopts a monomeric structure with two carboxylate oxygen atoms coordinated to tin in monodenate form from equatorial positions, and the coordination number is raised to six as the oxygen of water and pyridine nitrogen occupies the other equatorial positions of octahedron.
