In the title compound, C45H40N4O5, the cyclo-hexane entity on the (3-cyano-2,5-dihydro-furan-2-yl-idene)propane-dinitrile group, which replaces the usual dimethyl substituents, has not perturbed the delocalization geometry significantly. Weak inter-molecular inter-actions, viz. C-H⋯N(cyano), C-H⋯O(ether), C-H⋯π and π-π [between the aromatic rings with the shortest centroid-centroid distance of 3.603 (3) Å], consolidate the crystal packing, which exhibits voids of 57 Å(3).
在标题化合物C₄₅H₄₀N₄O₅中，(3-氰基-2,5-二氢呋喃-2-亚基)丙二腈基团上的环己烷实体取代了常见的二甲基取代基，并未显著扰乱离域几何结构。弱分子间相互作用，即C-H⋯N(氰基)、C-H⋯O(醚)、C-H⋯π和π-π[在芳香环之间，最短质心距离为3.603 (3) Å]，巩固了晶体堆积，其显示出57 ų的空隙。
