چکیده
The title mol-ecule, C(14)H(11)FN(2), is approximately planar except the ethyl group, the maximum atomic deviation being 0.105 (5) Å. The fluoro-phenyl ring and 2-propyl-idene-malononitrile unit are located on the opposite sides of the C=C double bond, showing an E configuration.

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 ...

There are two independent but virtually identical mol-ecules in the asymmetric unit of the title compound, C(13)H(19)ClN(2). Each mol-ecular skeleton displays an approximately planar structure except for the methyl group [the r.m.s. deviations for all 16 non-H atoms are 0.039 (mol-ecule 1) and 0.056 Å (mol-ecule 2)]. An E configuration is found about each of the C=C bonds. The crystal packing i...

In the title complex, C(17)H(12)N(2), the non-aromatic six-membered ring adopts an envelope conformation. The dihedral angle between the eight-membered plane containing the malononitrile group and the aromatic system is 25.88 (4)°. The distance from the central C atom of the malononitrile group to the centroid of the n-glide-related distal aromatic ring is 3.66 Å, suggesting π-π inter-actions.
