N-(4,5-Diazafluoren-9-ylidene)aniline

In the mol-ecule of the title compound, C(17)H(11)N(3), the 4,5-diaza-fluorenyl-idene unit is nearly planar and is oriented with respect to the phenyl ring at a dihedral angle of 75.75 (3)°. In the crystal structure, the mol-ecules are aligned in the [100] direction in such a way that neighbouring 4,5-diaza-fluorenyl-idene planes face each other in an anti-parallel fashion.
