Area of Science:

• Inorganic Chemistry
• Coordination Chemistry
• Materials Science

Background:

• Silver(I) complexes with sulfur-donor ligands exhibit diverse pharmacological properties.
• Ligand type and replacement ease are key to tuning biological activity.
• Silver thiosaccharinates form various mono- to polynuclear structures.

Purpose of the Study:

• To synthesize and characterize a novel two-dimensional Ag(I)-thiosaccharinate coordination polymer.
• To investigate the structural features, including silver-silver interactions and topology.
• To analyze the vibrational spectroscopic properties.

Main Methods:

• Synthesis of the silver(I) coordination polymer.
• Single-crystal X-ray diffraction for structural determination.
• Vibrational spectroscopy (Raman) for analysis of low-frequency spectrum.

Main Results:

• A two-dimensional coordination polymer, [Ag2(C7H4NO2S2)2(C10H8N2)1.5]n, was successfully synthesized.
• The structure exhibits an unusually short Ag...Ag separation (2.8859 Å), indicative of argentophilic interactions.
• Topological analysis revealed a threefold entangled 2D→2D mesh structure.

Conclusions:

• The synthesized silver thiosaccharinate complex displays unique structural characteristics.
• The short Ag...Ag distance suggests significant argentophilic bonding.
• The interpenetrating network topology adds complexity to the material's structure.
