Abstract: The asymmetric unit of the title complex, (C₂H₆N₅)(H₃O)[Co(C₇H₃NO₄)₂]·C₇H₅NO₄·H₂O, contains a Co^II ion coordinated by four O atoms and two N atoms from two dipicolinate ligands in a disorted octahedral environment, a protonated triazole molecule, a neutral pyridine-2,6-dicarboxylic acid molecule, a hydroxonium ion and a solvent water molecule. In the crystal, the components are linked into a three-dimensional framework by intermolecular O-HO, N-HO and N-HN and weak C-HO hydrogen bonds. In addition, - stacking interactions with centroid-centroid distances in the range 3.4809 (7)-3.8145 (6) Å are observed.
