摘　　要：The title compound （E）-N1,N4-bis（2,3,4-trimethoxy-6-methylbenzylidene） butane- 1,4- diamine （C26H36N2O6, Mr = 472.57） was synthesized and characterized by elemental analysis, IR spectra and single-crystal X-ray diffraction. The crystal belongs to triclinic, space group C2/c with a = 36.102（4）, b = 5.6620（11）, c = 13.015（2）A,β = 105.491 （2）°, V = 2563.7（7）A3, Z = 4, Dc = 1.224 g/cm3, 2 = 0.71073 A,μ（MoKα） = 0.087 mm^-1, F（000） = 1016, the final R = 0.0456 and wR = 0.1257 for 2255 observed reflections with I 〉 2σ（I）. X-ray diffraction analysis reveals that the molecule adopts an E configuration about the central C=N functional bond. The phenyl rings of two 2,3,4-trimethoxy-6-methylbenzaldehyde groups are parallel by symmetry. The molecules are linked through π-π and C-H…π stacking interactions and C-H…O hydrogen bonding interactions. The title compound possesses moderate antibacterial activity.The title compound （E）-N1,N4-bis（2,3,4-trimethoxy-6-methylbenzylidene） butane- 1,4- diamine （C26H36N2O6, Mr = 472.57） was synthesized and characterized by elemental analysis, IR spectra and single-crystal X-ray diffraction.
