3,5-Diamino-4H-1,2,4-triazol-1-ium hydroxonium bis­(pyridine-2,6-di­carboxyl­ato)cobaltate(II) pyridine-2,6-dicarb­oxy­lic acid monohydrate

The asymmetric unit of the title complex, (C(2)H(6)N(5))(H(3)O)[Co(C(7)H(3)NO(4))(2)]·C(7)H(5)NO(4)·H(2)O, 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—H⋯O, N—H⋯O and N—H⋯N and weak C—H⋯O hydrogen bonds. In addition, π–π stacking inter­actions with centroid–centroid distances in the range 3.4809 (7)–3.8145 (6) Å are observed.
