Abstract: The title compound, [Zn(C₇H₃NO₄)(C₁₂H₁₆N₃O)(H₂O)₃], was prepared from the imino nitroxide radical ligand 2-(4-pyridyl)-4,4,5,5-tetramethylimidazoline-1-oxyl, zinc(II) perchlorate and potassium pyridine-2,5-dicarboxylate. The Zn^II ion exists in a distorted octahedral coordination geometry with one pyridyl N atom from a radical ligand, one N and one O atom from a bidentate pyridine-2,5-dicarboxylate ligand and three O atoms from water molecules. A two-dimensional network is formed through O-HO hydrogen-bonding interactions.
