Abstract
The new β-diketone-functionalized pyridinecarboxylate ligand 2-(3-oxo-3-phenyl-propionyl)-6-pyridinecarboxylic acid ( H 2 L ) has been synthesized and fully characterized. Its tetranuclear and trinuclear nickel(II) coordination compounds [Ni 4 L 4 (DMF)(H 2 O) 3 ]·2.5DMF·3H 2 O (1) and [Ni 3 L 2 (OAc) 2 (DMF) 2 (H 2 O) 2 ]·DMF·H 2 O (2) have also been synthesized and characterized by single crystal X-ray diffraction. Compound 1 has a [2 × 2] molecular grid structure and 2 is a trinuclear structure. The magnetic properties study of 1 and 2 revealed the intramolecular antiferromagnetic exchange coupling between the Ni(II) ions exists.
