N,N'-Bis[(E)-4-cyanobenzylidene]urea

D.-H. Wu and L. Hu

Abstract: The molecule of the title compound, C17H10N4O, has crystallographically imposed C2 symmetry. The urea group and the benzene ring are nearly coplanar, the dihedral angle between them being 4.15 (7)°. The crystal packing is stabilized by aromatic [pi]-[pi] stacking interactions, with a centroid-to-centroid separation of 3.833 (4) Å.
