Abstract: In the title compound, C18H16N2, there are two independent half-mol­ecules (A and B) in the asymmetric unit, each mol­ecule being completed by an inversion center situated in the mid-point of the central N-N bond. The mol­ecules themselves therefore are essentially planar with r.m.s. deviations of 0.015 (1) and 0.020 (1) Å, respectively. In the crystal, mol­ecules are connected via C-H...[pi] inter­actions in which only type B mol­ecules are donors, while both A and B mol­ecules act as acceptors. As a result, type B mol­ecules are linked into infinite chains along b, which are inter­connected by molecules of type A.
