The asymmetric unit of the title compound, (C(6)H(9)N(2))[Co(C(7)H(3)NO(4))(C(7)H(4)NO(4))]·C(7)H(5)NO(4)·3H(2)O, contains one (6-carb-oxy-pyridine-2-carboxyl-ato)(pyridine-2,6-dicarboxyl-ato)cobaltate(II) anion, one phenyl-hydrazinium cation, one pyridine-2,6-dicarb-oxy-lic acid mol-ecule and three uncoordin-ated water mol-ecules, part of which are disordered. The Co(II) ion is coordinated by a pyridine-2,6-dicarboxyl-ate ion and a 6-carb-oxy-pyridine-2-carboxyl-ate ligand almost perpendicular to each other [the angle between the least-squares planes is 87.38 (4)°] and is surrounded by two O atoms and two N atoms in the equatorial plane and two O atoms in axial positions, resulting in a distorted octa-hedral coordination geometry. There is an extensive three-dimensional network of O-H⋯O and N-H⋯O hydrogen bonds, which link the components.
标题化合物(C₆H₉N₂)[Co(C₇H₃NO₄)(C₇H₄NO₄)]·C₇H₅NO₄·3H₂O的不对称单元包含一个(6-羧基吡啶-2-羧酸根)(吡啶-2,6-二羧酸根)钴(II)阴离子、一个苯肼鎓阳离子、一个吡啶-2,6-二羧酸分子和三个未配位的水分子，其中部分水分子无序。Co(II)离子由一个吡啶-2,6-二羧酸根离子和一个几乎相互垂直的6-羧基吡啶-2-羧酸根配体配位[最小二乘平面之间的夹角为87.38 (4)°]，在赤道平面上被两个O原子和两个N原子以及轴向位置的两个O原子包围，形成扭曲的八面体配位几何构型。存在广泛的O—H⋯O和N—H⋯O氢键三维网络，将各组分连接起来。
