In the centrosymmetric title complex, [Ni(C7H7N4O3)2 (C5H5N)2], the coordination geometry about the Ni2+ ion is octahedral, with two deprotonated 1-methyl-3-(p-nitrophenyl)triazenide 1-oxide ions, viz. [O2NC6H4NNN(O)CH3]-, acting as bidentate ligands (four-electron donors). Two neutral pyridine (py) molecules complete the coordination sphere in positions trans to each other. The triazenide 1-oxide ligand is almost planar, the largest interplanar angle of 8.80 (12)° being between the phenyl ring of the p-nitrophenyl group and the plane defined by the N3O moiety. The Ni-Ntriazenide, Ni-O and Ni-Npy distances are 2.0794 (16), 2.0427 (13) and 2.1652 (18) A, respectively.
