A new bishydrazone compound, N,N′-di[(E)-1-(2-hydoxyphenyl)methylidene]-2,6-naphthalenedicarbohydrazide (1), has been prepared by condensation reaction of 2,6-naphthalenedicarbohydrazide with salicylaldehyde in ethanol, and characterized by elemental analysis, FT-IR, 1H- and 13C-NMR, ESI–MS and single-crystal X-ray diffraction analysis. The crystal of 1·2DMF belongs to monoclinic, space group P2(1)/n with a = 10.454(1), b = 7.711(1), c = 18.801(2) Å, β = 93.364(1)°, V = 1512.9(3) Å3, Z = 2, D c = 1.314 g cm−3, μ = 0.093 mm−1, F(000) = 632, Mr = 598.65, the final R 1 = 0.0861 and wR 2 = 0.2279 for 7243 observed reflections with I > 2σ(I). The structural analysis reveals that compound 1·2DMF contains one N,N′-di[(E)-1-(2-hydoxyphenyl)methylidene]-2,6-naphthalenedicarbohydrazide molecule and two N,N-dimethylformamide solvent molecules. A 2D supramolecular structure of 1·2DMF was constructed by multiple intermolecular N–H···O and C–H···O hydrogen bonds.
