4,5-Diaza-9H-fluoren-9-imine

Abstract

In the title compound, C11H7N3, the diazafluorene rings are almost coplanar with an r.m.s. deviation of 0.0160 Å. In the crystal structure, C—H...N hydrogen bonds link molecules into sheets parallel to the ab plane. Molecules are also stacked regularly along the c axis by a variety of π–π interactions with centroid–centroid distances in the range 3.527 (2)–3.908 (2) Å.
