In the title complex, [Zn(N₃)₂(C₇H₁₀N₂)₂], the Zn^II atom is coordinated by two N atoms from two 4-(dimethylamino)pyridine (DMAP) ligands and by two N atoms from two azide anions in a distorted tetrahedral coordination geometry. In the crystal, weak C-HN hydrogen bonds between the DMAP and azide ligands link these discrete complex molecules into a three-dimensional supramolecular network.
