Abstract: The asymmetric unit of the title compound, (C₈H₈N₅)₂[Ce(NO₃)₅(H₂O)₂], contains one independent protonated 4-pyridylmethyleneamino-1,2,4-triazole cation and half of a centrosymmetric [Ce(NO₃)₅(H₂O)₂]^2- anion. The Ce atom coordinated by five NO₃^- anions and two water molecules, exhibiting a distorted 10-coordination. In the crystal structure, intermolecular O-HN and N-HO hydrogen bonds result in the formation of a supramolecular structure.
