Supramolecular organotin(IV) framework derived from pyridine-2,6-bis(thiocarboxylate) ligand

New trimetallic complexes, [R2SnPdtc]3 [where R = Me (1), n-Pr (2) and n-Bu (3), Pdtc = Pyridine-2,6-bis(thiocarboxylate)] have been prepared and characterized by FTIR, and NMR spectroscopies. Molecular structure of the complex 2 has been determined by single crystal X-ray diffraction and interactions of complex 2 with different metal ions in solution have been studied by UV–visible spectroscopic technique. Interactions of metal ions with 2 were dependent on the nature and bonding behavior of the added metal ions.

Dialkyltin complexes, [R2SnPdtc]3 have been prepared and characterized. The complexes possesses trimeric cyclic structure in the solid state. Hydrogen bonding results in the formation of a 2D sheet possessing cavities of two different radii. Interactions of the complex with different metal ions in solution have been studied which depend on the nature and bonding behaviour of the added metal ions.Figure optionsDownload as PowerPoint slideHighlights
