The binuclear title compound, [Cu2(C7H4N3O2)4(C3H7NO)2], is a discrete metal-organic compound having a paddle-wheel-type structure. The Cu...Cu distance is 2.6366 (5) Å and an inversion center is located at the mid-point of this bond. The CuII cation is coordinated by four carboxylate O atoms from four 4-azidobenzoate ligands, and one O atom from a dimethylformamide molecule, forming an overall distorted octahedral geometry when the Cu...Cu bond is also considered.
