(E)-5-[3-Cyano-2-(dicyanomethylene)-1-oxaspiro[4.5]dec-3-en-4-yl]-3-(1-methyl-1,4-dihydropyridin-4-ylidene)pent-4-en-1-yl 3,5-bis(benzyloxy)benzoate

چکیده
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).

The title compound, C(42)H(36)N(4)O(5)·0.25CH(3)CN, crystallizes with a partial twofold disordered (1/4) acetonitrile solvent of crystallization. The linking atoms to the 3,5-bis-(benz-yloxy)benzoic acid are disordered between two conformations in the ratio 0.780 (6):0.220 (6). In the crystal, the mol-ecules pack using mainly C-H⋯N(cyano) inter-actions coupled with weak C-H⋯O(ether) inter-actio...
