Özet

N-trans-cinnamylidene-m-toluidine (1) C16H15N, and N-trans-cinnamylidene-m-chloroaniline (2) C15H12NCl form isomorphous crystals which are monoclinic, space group P2(1)/c, with unit cell dimensions a = 5.967(2), b = 13.793(3), c = 15.048(5) Angstrom, beta = 91.97(3)degrees and a 5.868(2), b = 13.788(4), c = 15.191(4) Angstrom, beta = 91.87(3)degrees, respectively. The single-crystal X-ray structure determinations of the title compounds reveal trans structures. Ring (A) C-10-15 and ring (B) C-1-6, are practically planar in both structures with dihedral angles of 61.3(3) and 63.6(2)degrees, respectively. H-1 nmr, u.v. and i.r. spectra are also reported.
