Abstract: The 4-carboxyimidazole-5-carboxylate(2-) dianion in the title compound, [Ni(C₅H₂N₂O₄)(C₁₆H₃₆N₄)]·H₂O, N,O'-chelates to the Ni^II atom, which shows an octahedral coordination. The macrocycle folds itself around the metal atom and binds to it through four secondary nitrogen atoms; adjacent molecules are linked by N-HO hydrogen bonds into a linear chain. The water molecule is disordered over two positions.
