The mol-ecule of the title Schiff base compound, C(16)H(12)Cl(4)N(2), lies across an inversion centre and adopts an E configuration with respect to the azomethine C=N bond. The imine groups are coplanar with the aromatic rings. Within the mol-ecule, the planar units are parallel but extend in opposite directions from the dimethyl-ene bridge. In the crystal structure, mol-ecules are linked together by inter-molecular C-H⋯Cl hydrogen bonds along the a axis.
标题席夫碱化合物C(16)H(12)Cl(4)N(2)的分子位于一个对称中心上,相对于偶氮甲碱C=N键呈E构型。亚胺基团与芳环共面。在分子内,平面单元相互平行,但从亚甲基桥向相反方向延伸。在晶体结构中,分子沿a轴通过分子间C-H⋯Cl氢键连接在一起。
