Abstract: | 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) Å, respectively. |
