摘要: The synthesis, crystal structure analysis and characterization of a monoazo dye, 4-((2,6-dichloro-4-nitro phenyl)azo)-N-(diacetyl oxygen ethyl)aniline, are reported. dye crystallised in the triclinic system, space group P-1 with a=8.1663(3) A, b= 9.4222(3) c=15.4694(5) α=78.9130(10)°, β=75.019(2)°, γ=70.787(2)°, V=1078.26(6) A3 Z=2. There is only one molecule asymmetric unit. dihedral angle between two phenyl rings 53.4 A. In structure, intermolecular C-H…O hydrogen bonds link molecules into centrosymmetric dimers, forming R22(30) ring motifs, which they may be effective stabilization structure. Between rings, π…π stacking (interactions) further stabilize
