title: (E)-5-[3-Cyano-2-(dicyano-methyl-ene)-1-oxaspiro-[4.5]dec-3-en-4-yl]-3-(1-methyl-1,4-dihydro-pyridin-4-yl-idene)pent-4-en-1-yl 3,5-bis-(benz-yloxy)benzoate.
abstract: 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).
