Abstract: In the title compound, [Cu(C₈H₄O₄)(C₁₄H₈N₄)(H₂O)]·C₄H₉NO·H₂O, the Cu^II atom is five-coordinated by three O atoms from two benzene-1,3-dicarboxylate (1,3-bdc) ligands and one water molecule, and two N atoms from one chelating pyrazino[2,3-f][1,10]phenanthroline (L) ligand in a distorted square-pyramidal geometry. The Cu^II atoms are bridged by the 1,3-bdc ligands to form a one-dimensional helical chain structure. A network of O-HO hydrogen bonds completes the structure. There are two half-molecules of 1,3-bdc in the asymmetric unit; both complete molecules are generated by twofold rotation symmetry, with two C atoms lying on the rotation axis in each case.
