2-[3-((Z)-2-{4-[Bis(2-chloroethyl)amino]phenyl}ethenyl)-5,5-dimethylcyclohex-2-en-1-ylidene]propanedinitrile

The highly conjugated title compound, C23H25Cl2N3, is nearly planar (the mean deviation from the plane being 0.049 Å), except for the –C(CH3)2 group on the cyclohexene ring and the two CH2Cl groups. The cyclohexene ring has an envelope configuration. In the crystal, the packing is stabilized by C—H...Cl interactions and C—H...π interactions involving the benzene ring.
