Abstract: In the title compound, [Zn(C₇H₄O₆S)(C₁₉H₁₂N₄)₂(H₂O)], the Zn^II ion is coordinated by two N,N'-bidentate 2-phenyl-1H-1,3,7,8-tetraazacyclopenta[l]phenanthrene ligands, one O-monodentate 5-sulfosalicylate dianion and a water molecule. This results in a distorted cis-ZnO₂N₄ octahedral coordination geometry for the metal ion. In the crystal, molecules are expanded into a three-dimensional supramolecular motif via O-HO, O-HN and N-H(O,S) hydrogen bonds. In addition, - stacking interactions between the aromatic rings of the polycyclic ligands consolidate the sturcture [shortest centroid-centroid distance = 3.501 (2) Å].
