Abstract: In the title compound, [Cu₂(C₁₃H₁₁N₄S)₂(N₃)₂], the Cu^II cation is N,N',S-chelated by the deprotonated Schiff base ligand and is coordinated by the azide anion, while an N atom from an adjacent azide anion bridges the Cu^II cation at the apical position with a longer Cu-N distance of 2.533 (3) Å, completing the distorted N₄S square-pyramidal coordination geometry. A pair of azide anions bridge the two Cu^II cations, forming a centrosymmetric binuclear molecule. In the crystal, the binuclear molecules are linked by an N-HN hydrogen bond into a ribbon running along the a axis.
