Abstract: In the title complex, {[Ni(C₇H₂N₂O₇)(C₁₀H₈N₂)(H₂O)]·0.2H₂O}_n, the Ni^II atom is coordinated by three O atoms from two symmetry-related 3,5-dinitrosalicylate ligands, two N atoms from one 2,2'-bipyridine and one water molecule, and its environment displays a distorted octahedral geometry. The short face-to-face distances between parallel 2,2'-bipyridine planes of neighbouring complexes and neighbouring one-dimensional chains indicate - stacking. The packing is further influenced by inter- and intramolecular hydrogen-bond interactions.
