Abstract

Utilizing Co(2-mpac)2(H2O)2 as molecular building block, a coordination polymer, [Co2(2-mpac)4(4,4′-bpy) · 2H2O] n (1) (2-mpac = 5-methyl-2-pyrazinecarboxylic acid; 4,4′-bpy = 4,4′-bipyridine), was synthesized and structurally characterized by X-ray single crystal diffraction. Elemental analysis, infrared, and magnetism are presented. Variable temperature magnetic susceptibility measurements exhibit weak antiferromagnetic interaction between Co centers in 1.
