Abstract

In the title complex, {[Zn(C7H3NO4)(C12H8N2)]·H2O}n, the ZnII ion is in a distorted octahedral environment, defined by two N atoms from a chelating 1,10-phenanthroline (phen) ligand and one N atom and three O atoms from two pyridine-2,3-dicarboxylate (2,3-pydc) ligands. The bridging 2,3-pydc ligands connect the ZnII ions into a chain extending along [010]. O—H...O hydrogen bonds between the uncoordinated water molecules and the uncoordinated carboxylate O atoms, as well as π–π interactions between the pyridine rings of the phen ligands [centroid–centroid distance = 3.557 (2) Å], are observed.
