Aqua(2-hydroxy-5-sulfonatobenzoato-κO1)bis(2-phenyl-1H-1,3,7,8-tetraazacyclopenta[l]phenanthrene-κ2N7,N8)zinc(II)

Abstract

In the title compound, [Zn(C7H4O6S)(C19H12N4)2(H2O)], the ZnII 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—H...O, O—H...N and N—H...(O,S) hydrogen bonds. In addition, π–π stacking interactions between the aromatic rings of the polycyclic ligands consolidate the sturcture [shortest centroid–centroid distance = 3.501 (2) Å].
