(E)-2-{3-[4-(Diphenyl-amino)styr-yl]-5,5-dimethyl-cyclo-hex-2-enyl-idene}-malono-nitrile.

In the title compound, C(31)H(27)N(3), the cyclo-hexene ring has an envelope configuration. In the crystal structure, there is an 34 Å(3) void around the inversion center, but the low electron density (0.13 e Å(-3)) in the difference Fourier map suggests no solvent mol-ecule occupying this void. No hydrogen bonding is found in the crystal structure.
