title: (1R,2R,E,E)-N,N'-Bis(4-chloro-benzyl-idene)cyclo-hexane-1,2-diamine.
abstract: The title Schiff base ligand, C(20)H(20)Cl(2)N(2), was prepared by condensation of commercially available p-chloro-benzalde-hyde and (R,R)-1,2-diammonium-cyclo-hexane mono-(+)-tartrate. The cyclo-hexane ring adopts a chair conformation. The dihedral angle between the two aromatic rings is 62.52 (8)°. The crystal structure is stabilized by an inter-molecular C-H⋯Cl hydrogen bond.
