Abstract
In the title complex, [Cu(C7H3NO5)(C14H12N2)]·3H2O, there are two independent neutral molecules of the Cu complex along with six molecules of water of hydration in the asymmetric unit. The CuII atoms in each complex adopt a distorted square-pyramidal coordination geometry being pentacoordinated by one N and two O atoms of 4-hydroxypyridine-2,6-dicarboxylate 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 interactions with centroid–centroid distances in the range 3.620 (1)–3.712 (1) Å. In addition, a C—H⋯π interaction between a heterocyclic ring of dmp is observed to reinforce the crystal cohesion.
