Abstract: The molecule of the title compound, [CuI(C₁₉H₂₀Cl₂N₂)], lies across a crystallographic mirror plane. The coordination around the copper centre is distorted trigonal planar, with a bite angle of 94.40 (7)°. A six-membered chelate ring is formed by the coordination of iminic N atoms of the bidentate ligand to the Cu^I atom, adopting a chair conformation. This conformation is required if the local symmetry of the metal coordination site is in accordance with a mirror plane that passes through the metal atom normal to the line connecting the N atoms. The dihedral angle between the benzene rings is 78.66 (5)°. The crystal structure is stabilized by weak intermolecular C-H interactions, which link the molecules into chains along the b axis.
