The asymmetric unit of the title Schiff base compound, C(20)H(18)N(4), contains one half-mol-ecule, lying across a crystallographic inversion centre and adopting an E configuration with respect to the C=N bonds. The imino group is coplanar with the benzene ring with a maximun deviation of 0.096 (1) Å for the N atom. Within the molecule, the planar units are parallel but extend in opposite directions from the methylene bridge. In the crystal structure, neighbouring mol-ecules are linked together by weak inter-molecular C-H⋯N hydrogen bonds involving the cyano N atoms, forming R(2) (2)(10) ring motifs.
标题席夫碱化合物C(20)H(18)N(4)的不对称单元包含半个分子，该分子位于一个晶体学反演中心上，且相对于C=N键呈E构型。亚氨基与苯环共平面，N原子的最大偏差为0.096 (1) Å。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，相邻分子通过涉及氰基N原子的弱分子间C-H⋯N氢键连接在一起，形成R(2) (2)(10)环 motif。
