[N,N'-Bis(4-chlorobenzylidene)-2,2-dimethylpropane-1,3-diamine-κN,N']iodidocopper(I).

The mol-ecule of the title compound, [CuI(C(19)H(20)Cl(2)N(2))], 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 inter-molecular C-H⋯π inter-actions, which link the mol-ecules into chains along the b axis.
