Abstract: In the title compound, [Fe(C₆H₂N₂O₄)(C₁₈H₁₀N₄)(H₂O)]_n, the Fe^II ion adopts a slightly distorted octahedral mer-FeN₃O₃ geometry, arising from one N,N'-bidentate dipyrido[3,2-a:2',3'-c]phenazine ligand, one N,O-chelating pyrazine-2,3-dicarboxylate dianion and one water molecule. An O-bonded symmetry-related dianion completes the coordination of the metal. The bridging dianion results in a one-dimensional polymeric chain. Aromatic - stacking interactions between ligands [centroid-centroid separations = 3.528 (2) and 3.741 (2) Å] and O-HO and O-HN hydrogen bonds link the chains together, leading to a three-dimensional supramolecular network.
