Abstract: The reaction of Co(NO₃)₂·3H₂O with pyridine-2,6-dicarboxylic acid and 3,5-dimethyl-1H-pyrazole in a 1:1:3 molar ratio affords the title complex, [Co(C₇H₃NO₄)(C₅H₈N₂)₃]·H₂O. The Co^II atom is coordinated by one pyridine-2,6-dicarboxylate chelating ligand and three 3,5-dimethyl-1H-pyrazole ligands in a distorted octahedral geometry. Hydrogen-bonding interactions involving the coordinated carboxylate group, 3,5-dimethyl-1H-pyrazole and water help to consolidate the crystal structure
