Abstract
Reaction of thiodiglycolic acid and silver nitrate under ultrasonic condition forms a 3D supramolecular framework of silver with composition [Ag2(tdga)] n (1). X-ray single crystal structure analysis reveals repetition of paddle wheel units in the network. A weak Ag–Ag bond is present in the complex. A new μ8-coordination mode of the thiodiglycolate ligand is identified. Photoluminescence and thermal characterization of the complex was examined. Novel 3D silver coordination polymer with Ag–Ag bond is synthesized using thiodiglycolic acid ligand and characterized by X-ray diffraction, IR, photoluminescence and TG analysis. The ligand displays a unique type of coordination.
