A new Zn(II) nitronyl nitroxide complex [Zn(NIT4Py)(PDA)(H2O)3] (NIT4Py = 2-(4′-pyridyl)-4,4,5,5-tetramethylimidazoline-1-oxyl-3-oxide, H2PDA = pyridine-2,5-dicarboxylic acid) has been synthesized and structurally characterized by X-ray diffraction. It crystallizes in monoclinic, space group P21/c with a = 16.881(8), b = 7.356(4), c = 18.857(9) ?, a = 108.616(6)o, V = 2219.1(19) ?3, C19H25N4O9Zn, Mr = 518.80, Dc = 1.553 g/cm3, ì(MoKá) = 1.165 mm-1, F(000) = 1076, Z = 4, the final R = 0.0269 and wR = 0.0715 for 3193 observed reflections with I > 2ó(I). The complex exists as discrete mononuclear molecules and the zinc(II) ion is six-coordinated with one radical ligand (NIT4Py), one bidentate pyridine-2,5-dicarboxylate anion and three water molecules. A three-dimensional network structure is formed through the intermolecular interactions.
