Abstract:	A novel copper(II)-radical complex Cu(NITmPy)(PDA)(H₂O)] · (H₂O) (1) (NITmPy = 2-(3′-pyridyl)-4,4,5,5-tetramethylimidazoline-1-oxyl-3-oxide, H₂PDA = 2,6-pyridinedicarboxylic acid) has been synthesized and structurally characterized by X-ray diffraction methods. It crystallizes in the triclinic space group . The Cu(II) ion exists in a distorted square pyramid environment. The molecules of Cu(NITmPy)(PDA)(H₂O)] · (H₂O) are connected as a two-dimensional structure by the intermolecular hydrogen bonds. Magnetic measurements show intramolecular ferromagnetic interactions between NITmPy and Cu(II) ion and intermolecular antiferromagnetic interactions in 1.

Keywords:	Copper(II) Nitronyl nitroxide radical PDA Crystal structure Ferromagnetic interaction
