In the title racemic Schiff base ligand, C20H20Cl2N2, which was
prepared by the condensation of 2-chlorobenzaldehyde and
cyclohexane-1,2-diamine, the cyclohexane ring adopts a chair
conformation and the dihedral angle between the aromatic
rings of the 2-chlorophenyl substituent groups is 62.52 (8). In
the structure, there are two short intramolecular methine C—
H Cl interactions [C Cl = 3.066 (2) and 3.076 (3) A ° ], and
in the crystal there are also weak intermolecular aromatic C—
H Cl [3.464 (3), 3.553 (3) and 3.600 (3) A ° ] and Cl Cl
[3.557 (3) and 3.891 (3) A ° ] contacts.
