4,5-Diazafluoren-9-ol.
The title compound, C(11)H(8)N(2)O, has two crystallographically independent molecules in the crystal. Each molecule is basically planar except for the O atom. The two N atoms in the molecule show different behaviour as hydrogen-bonding acceptors. One of them is involved in intermolecular O-H.N hydrogen bonds which stabilize the crystal packing.
