2,2′-Dichloro-1,1′-[(butane-1,4-diyldi­oxy)bis­(nitrilo­methyl­idyne)]dibenzene

Abstract

The mol-ecule of the title compound, C(18)H(18)Cl(2)N(2)O(2), lies across a crystallographic inversion centre and adopts an E configuration with respect to the azomethine C=N bond. The imino group is coplanar with the aromatic ring. Within the mol-ecule, the planar units are parallel, but extend in opposite directions from the dimethyl-ene bridge. In the crystal structure, the title compound exhibits a layer packing structure via weak π-π stacking inter-actions [inter-molecular plane-to-plane distances between adjacent aromatic rings are 3.461 (3) Å]. Mol-ecules in each layer are linked by inter-molecular C-H⋯O hydrogen-bonding inter-actions.
