Abstract

In the title molecule, C13H9NO, the fluorene system and the oxime group non-H atoms are essentially coplanar, with a maximum deviation from the fluorene mean plane of 0.079 (2) Å for the oxime O atom. A short intramolecular C - H⋯O generates an S(6) ring. In the crystal, molecules related by a twofold screw axis are connected by O - H⋯N hydrogen bonds, forming [100] chains Within these chains, molecules related by a unit translation along [100] show π-π stacking interactions between their fluorene ring systems with an interplanar distance of 3.347 (2) Å. The dihedral angle between the fluorene units of adjacent molecules along the helix is 88.40 (2)°. There is a short C - H⋯π contact between the fluorene groups belonging to neighbouring chains.
