In the title compound, [Cu(C2H3O3)(C12H8N2)2]NO3, the CuII atom is coordinated by two phenanthroline (phen) ligands and one carboxyl-O atom of a hydroxyacetate anion in a distorted square-pyramidal geometry. The hydroxy group of the hydroxyacetate ligand links with the counter NO3− anion via a pair of bifurcated O—H⋯O hydrogen bonds. The centroid–centroid distance of 3.5676 (14) Å between benzene rings of parallel phen ligands of adjacent molecules suggests the existence of π–π stacking. Weak intermolecular C—H⋯O hydrogen bonding is also present in the crystal structure.
