Abstract: The title complex, [Ni₂(C₄H₈N₄O₂)₆](NO₃)₄·2CH₄O, contains a centrosymmetric binuclear nickel(II) complex bridged by a pair of 4-amino-3,5-bis(hydroxymethyl)-1,2,4-triazole ligands. The separation between the Ni^II atoms is 3.962 (1) Å. The Ni atoms are in a slightly distorted octahedral coordination. Intermolecular N-HO, N-HN and O-HO hydrogen bonds connect the ligands, solvent molecules and nitrate ions.
