Supramolecular design and biological activity of coordination polymer based on dimethyltin (IV) and N-donor ligand

The supramolecular polymer of the type [Me2SnCl2L], 1, L = 2,2'-bipyridine (2,2'-bpy), has been synthesized by the reaction of dimethyltin (IV) dichloride and 5-nitroisophthallic acid in the presence of sodium ethoxide and 2,2'-bpy. The compound was structurally characterized by elemental analysis, FT-IR spectra and X-ray single crystal. The x-ray data exhibited 1:1 stoichiometry for the dimethyltin dichloride: 2,2'-bpy ligands. The structure of 1 extends along the a-axis in a parallel way forming 1D-chains via H-bonds while they further propagate creating 2D- network via extensive H-bonds. The biological activity against some fungi and bacterial microorganisms has been also studied.
