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 coordin-ated by four O atoms and two N atoms from two dipicolinate ligands in a disorted octa-hedral environment, a protonated triazole mol-ecule, a neutral pyridine-2,6-dicarb-oxy-lic acid mol-ecule, a hydroxonium ion and a solvent water mol-ecule. In the crystal, the components are linked into a three-dimensional framework by inter-molecular O-H⋯O, N-H⋯O and N-H⋯N and weak C-H⋯O hydrogen bonds. In addition, π-π stacking inter-actions with centroid-centroid distances in the range 3.4809 (7)-3.8145 (6) Å are observed.
标题配合物(C₂H₆N₅)(H₃O)[Co(C₇H₃NO₄)₂]·C₇H₅NO₄·H₂O的不对称单元包含一个Co(II)离子，在扭曲的八面体环境中由两个吡啶二甲酸配体的四个O原子和两个N原子配位，一个质子化的三唑分子，一个中性的吡啶 - 2,6 - 二羧酸分子，一个水合氢离子和一个溶剂水分子。在晶体中，各组分通过分子间的O - H⋯O、N - H⋯O和N - H⋯N以及弱的C - H⋯O氢键连接成三维骨架。此外，观察到质心 - 质心距离在3.4809 (7) - 3.8145 (6) Å范围内的π - π堆积相互作用。
