• Coordination polymer
• Diglycolic acid
• Ag-Ag bond
• Photoluminescence

Reaction of diglycolic acid (dgaH(2)) and silver nitrate under ultrasonic condition forms a 3D supramolecular complex of composition [Ag-4(dga)(2)] (n) (1) (dgaH(2) = diglycolic acid). The structure of the complex was determined by single crystal X-ray diffraction analysis. Structural study reveals that two types of Ag(I) centers are present. Short silver-silver bond is present in the compound. It is observed that the 2D layers formed by silver(I) and dga(2-) ions interact further to form an overall 3D network. A new octadentate coordination mode of diglycolate ligand is identified. Photoluminescent and thermogravimetric characterization of the complex have been done. %26lt;br%26gt;New 3D silver coordination polymer of silver(I) having ligand supported Ag-Ag bond has been synthesized using diglycolic acid ligand and characterized by X-ray diffraction, photoluminescence and TG analysis. The ligand shows new type of coordination in the complex .
