Crystal and molecular structure of N-(p-chlorobenzylidene)-3-chloro-4-fluoroaniline

The crystal structure of the title compound [C13H8Cl2FN] has been determine d at room temperature. Colourless, needle like crystals of the compound are monoclinic, space group P21/c with unit cell dimensions a = 3.878(4) Angst rom, b = 12.210(5) Angstrom, c = 24.528(6) Angstrom beta = 91.40(4)degrees, Z = 4 and D-c = 1.534 Mgm(-3) (Direct methods; full-matrix least-squares; R = 0.0547; 1443 hkl). The two planar phenyl rings make a dihedral angle of 10.70(3)degrees. The atoms Cl(2) and F attached to one of the phenyl rings have deviations -0.008(11) Angstrom and 0.019(11) Angstrom, respectively. Cl(1) attached to the other phenyl ring has a deviation of -0.028(10) Angst rom. The molecules are packed in layers parallel to (101) plane, and form C -H...F bonds.
