Rac-(E,E)-N,N'-Bis(2-chloro-benzyl-idene)cyclo-hexane-1,2-di-amine.

ABSTRACT: In the title racemic Schiff base ligand, C20H20Cl2N2, which was prepared by the condensation of 2-chloro-benzaldehyde and cyclo-hexane-1,2-di-amine, the cyclo-hexane ring adopts a chair conformation and the dihedral angle between the aromatic rings of the 2-chloro-phenyl substituent groups is 62.52?(8)°. In the structure, there are two short intra-molecular methine C-H?Cl inter-actions [C?Cl = 3.066?(2) and 3.076?(3)?Å], and in the crystal there are also weak inter-molecular aromatic C-H?Cl [3.464?(3), 3.553?(3) and 3.600?(3)?Å] and Cl?Cl [3.557?(3) and 3.891?(3)?Å] contacts.
