We prepared metal organic frameworks such as copper(II) monocarboxylate (formate and benzoate) pyridine derivatives and zinc(II) monocarboxylate (p-phenyl benzoate and benzoate) pyridine derivatives. These complexes were synthesized at room temperature using pyridine or p-phenyl pyridine to grow single crystals that were then analyzed using single-crystal X-ray analysis. These structures are formed by hydrogen bonding and the self-assembly of pi-stacking of mononuclear units. The magnetic susceptibilities of the copper(II) complexes obeyed the Curie-Weiss law over the range of 2-300 K . The Weiss constants indicated the existence of small antiferromagnetic interactions arising from the hydrogen bonding.
