In the title complex, [Cu(C(7)H(3)NO(5))(C(14)H(12)N(2))]·3H(2)O, there are two independent neutral mol-ecules of the Cu complex along with six mol-ecules of water of hydration in the asymmetric unit. The Cu(II )atoms in each complex adopt a distorted square-pyramidal coordination geometry being penta-coordinated by one N and two O atoms of 4-hydroxy-pyridine-2,6-dicarboxyl-ate anions and two N atoms of 2,9-dimethyl-1,10-phenanthroline (dmp) molecules. In the crystal structure, there are O-H⋯O and C-H⋯O hydrogen bonds and five π-π stacking inter-actions with centroid-centroid distances in the range 3.620 (1)-3.712 (1) Å. In addition, a C-H⋯π inter-action between a heterocyclic ring of dmp is observed to reinforce the crystal cohesion.
在标题配合物[Cu(C₇H₃NO₅)(C₁₄H₁₂N₂)]·3H₂O中，不对称单元中有两个独立的铜配合物中性分子以及六个结晶水分子。每个配合物中的Cu(II)原子采用扭曲的四方锥配位几何构型，由4-羟基吡啶-2,6-二羧酸根阴离子的一个N原子和两个O原子以及2,9-二甲基-1,10-菲啰啉（dmp）分子的两个N原子进行五配位。在晶体结构中，存在O—H⋯O和C—H⋯O氢键以及五个质心间距在3.620 (1) - 3.712 (1) Å范围内的π-π堆积相互作用。此外，观察到dmp杂环之间的C—H⋯π相互作用增强了晶体的内聚力。
