Abstract :
The new β-diketone-functionalized pyridinecarboxylate ligand 2-(3-oxo-3-phenyl-propionyl)-6-pyridinecarboxylic acid (H2L) has been synthesized and fully characterized. Its tetranuclear and trinuclear nickel(II) coordination compounds [Ni4L4(DMF)(H2O)3]·2.5DMF·3H2O (1) and [Ni3L2(OAc)2(DMF)2 (H2O)2]·DMF·H2O (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.
