Abstract
Abstract Crystals of C.I. Disperse Blue 79, a commercial aminoazobenzene dye, were grown from an ethyl acetate solution and the crystal structure was determined by single crystal X-ray diffraction analysis. The dye molecule crystallizes in the triclinic space group P -1 with the unit cell dimensions: a =11.467(2) A, b =11.952(2) A, c =12.372(2) A, α =101.047(4)°, β =113.221(4)°, γ =108.204(4)°. Results showed that the 4-nitro-4′-aminoazobenzene skeleton of the dye is quasi planar, with a dihedral angle of 9.4(3)° between two aromatic rings. The intra- and intermolecular hydrogen bonds, together with the interlayer aromatic π – π stacking interactions, stabilize the molecular conformation and packing in the crystal structure.
