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.
