Structural chemistry and magnetic properties of copper pyromellitate coordination polymers containing pyridylnicotinamide ligands

A series of divalent copper pyromellitate coordination polymers containing either 3-pyridylnicotinamide or 4-pyridylnicotinamide was structurally characterized. These show 1-D chain, dimer-based 2-D layer, or trimer-based rare frl 3-D topology depending on synthetic conditions.
