3-D Coordination polymer containing a 1-D tunnel filled with 4,4′-bpy: synthesis, crystal structure, and characterization

Abstract

A coordination polymer, [Co(2-mpac)₂(4,4′-bpy)·(4,4′-bpy)] _n (2-mpac: 5-methyl-2-pyrazinecarboxylic acid; 4,4′-bpy: 4,4′-bipyridine), has been synthesized through hydrothermal synthesis and structurally characterized by X-ray single crystal diffraction. Single crystal X-ray diffraction analysis reveals a 3-D network featuring a 1-D tunnel filled with 4,4′-bpy molecules. Elemental analysis, IR, thermogravimetric analysis, and magnetic properties are presented.
