Self-assembly and characterization of a novel 2D network polymer containing a 60-membered organotin macrocycle

The reaction of 1-(4-carboxyphenyl)-5-mercapto-1 H-tetrazole with trimethyltin chloride in the presence of sodium ethoxide in benzene affords a novel 2D organotin network structure complex 1, which is an unusual organotin network containing a hexanuclear 60-membered organotin macrocycle. The complex has been characterized by elemental analysis, IR, and (1)H, (13)C, and (119)Sn NMR spectroscopy. Furthermore, we have also characterized the complex by X-ray crystallography.
