title: (E,E)-1,4-Diethyl-1,4-diphenyl-2,3-diazabutadiene.
abstract: Molecules of the title compound [(E,E)-propiophenone azine], C(18)H(20)N(2), lie across centres of inversion in space group P2(1)/c. The conformations of similar simple azines are discussed in terms of the soft hydrogen bonds present in the structures.
