The 1‐Anilino‐3‐phenylimino propene‐(1) crystallizes in the Iba2 space group having the lattice constants a = 20.132 Å; b = 16.102 Å; c = 7.683 Å. The elementary lattice cell contains 8 molecules. The intensities were measured by means of an automatic fourcircle diffractometer. The structure was clarified by a direct phase determination. The refinement was carried out by means of the least squares method for 1532 symmetryindependent reflections up to an R ‐value of 0.10. The molecular structure is more similar to that of the asymmetric polymethine merocyanines, and less to the symmetrical polymethine cyanines. This is due to the different electronic structure of the amino and imino groups in the molecule. The molecules are electrically neutral. The intermolecular contacts are made through N‐H…N hydrogen bridges and van‐der‐Waals contacts between C‐ and H‐atoms.
