Synthesis and Crystal Structure of N,N′-4-aminomethyl-pyromellitic diimide

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/cm3, Z = 2, C22H14N4O4, Mr = 398.37,μ(MoKα) = 0.106mm-1 and F(000) = 412, and its structure was refined to R = 0.0469 and wR = 0.1017 for 1194observed reflections (Fo ＞ 4σ(Fo)). The X-ray diffraction shows the existence of the staggered multi-dimensional supramolecular network based on the Z-mode conformation of the title compound.
