摘要
The title compound N,N′-4-aminomethyl-pyromellitic diimide (4-pmpmd) crystallizes in monoclinic, space group P21/c with a = 4.785(1), b = 6.200(1), c = 29.907(2) A, β = 93.583(11)°, V= 885.5(2) A^3, Dc = 1.494 g/cm^3, Z= 2, C22H14N4O4, Mr = 398.37,/t(MoKα) = 0.106 mm^-1 and F(000) = 412, and its structure was refined to R = 0.0469 and wR = 0.1017 for 1194 observed reflections (F0 〉 4σ(F0)). The X-ray diffraction shows the existence of the staggered strong intermolecular C-H…O (DA) hydrogen bonds between adjacent molecules, the intermo- lecular C-H…π hydrogen bonds and the weak π…π stacking interactions, leading to the formation of multi-dimensional supramolecular network based on the Z-mode conformation of the title compound.
