2,2'-Dichloro-1,1'-[(butane-1,4-diyldi-oxy)bis-(nitrilo-methyl-idyne)]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 ?-? 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.
