ABSTRACT
The 4-carboxyimidazole-5-carboxylate(2−) dianion in the title compound, [Ni(C5H2N2O4)(C16H36N4)]·H2O, N,O′-chelates to the NiII 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—H...O hydrogen bonds into a linear chain. The water molecule is disordered over two positions.
