The dimeric title compound, [Cu2(C9H10N3O)2(N3)2], is located on a crystallographic inversion center. The Cu atom is coordinated by a tridentate anionic hydrazone ligand and two bridging azide ligands in a distorted square-pyramidal coordination geometry. The non-bonding CuCu distance is 3.238 (1) �. Non-classical intermolecular C-HN hydrogen bonds link the dimers into chains along the c axis.
