Poly[(μ(3)-quinoline-6-carboxyl-ato-κ(3)N:O:O')silver(I)]

Area of Science:

• Coordination chemistry
• Materials science
• Crystallography

Background:

• Coordination polymers are materials with diverse applications.
• Silver(I) coordination polymers exhibit interesting structural and electronic properties.
• Quinoline carboxylate ligands offer versatile coordination modes.

Purpose of the Study:

• To synthesize and characterize a new coordination polymer involving silver(I) and 6-quinoline-carboxylate.
• To elucidate the crystal structure and supramolecular assembly of the titled compound.
• To investigate the coordination geometry and intermolecular interactions within the polymer.

Main Methods:

• Single-crystal X-ray diffraction analysis was employed to determine the crystal structure.
• The coordination environment around the Ag(I) cation was analyzed.
• Intermolecular interactions, including π-π stacking, were investigated.

Main Results:

• A novel coordination polymer, [Ag(C(10)H(6)NO(2))](n), was successfully synthesized and characterized.
• The Ag(I) cation exhibits a distorted T-shaped coordination geometry (AgNO2), with an O-Ag-O angle of 160.44(9)°.
• The 6-quinoline-carboxylate anion acts as a bridge, forming a nearly planar polymeric sheet with Ag-Ag distances of 2.9200(5) Å.
• π-π stacking between quinoline rings was observed with a centroid-centroid distance of 3.7735(16) Å.

Conclusions:

• The study presents a new silver(I) coordination polymer with a unique sheet structure.
• The distorted T-shaped coordination geometry and observed π-π stacking are key features of this material.
• The findings contribute to the understanding of silver-based coordination polymers and their structural motifs.
