چکیده
In the title compound, C(11)H(7)N(3), the diaza-fluorene rings are almost coplanar with an r.m.s. deviation of 0.0160 Å. In the crystal structure, C-H⋯N hydrogen bonds link mol-ecules into sheets parallel to the ab plane. Mol-ecules are also stacked regularly along the c axis by a variety of π-π inter-actions with centroid-centroid distances in the range 3.527 (2)-3.908 (2) Å.
