Bis(pyridine-3-carboxylic acid-κN)silver(I) perchlorate

Area of Science:

• Coordination Chemistry
• Crystal Engineering
• Supramolecular Chemistry

Background:

• Silver(I) complexes are of interest due to their diverse coordination geometries and potential applications.
• Pyridine-3-carboxylic acid is a versatile ligand capable of forming various coordination modes and hydrogen bonding interactions.

Purpose of the Study:

• To elucidate the crystal structure and supramolecular assembly of the [Ag(pyridine-3-carboxylic acid)2]ClO4 complex.
• To investigate the role of hydrogen bonding and weak metal-ligand interactions in constructing the extended network.

Main Methods:

• Single-crystal X-ray diffraction analysis was employed to determine the molecular and crystal structure.
• Analysis of intermolecular interactions, including hydrogen bonds and Ag⋯O interactions, was performed.

Main Results:

• The silver(I) center exhibits an approximately linear coordination geometry with two nitrogen atoms from pyridine-3-carboxylic acid ligands.
• Complex cations form chains via hydrogen bonding between carboxyl groups.
• These chains assemble into a 3D network through C-H⋯O hydrogen bonds and Ag⋯O interactions (2.757(8) Å and 2.899(2) Å).

Conclusions:

• The study reveals a detailed 3D supramolecular network built upon a combination of coordination, hydrogen bonding, and weak silver-oxygen interactions.
• The findings contribute to understanding the crystal engineering principles governing the assembly of silver(I) coordination compounds.
