Crystal structure of N-(quinolin-6-yl)hydroxyl-amine.

The title compound, C9H8N2O, crystallized with four independent mol­ecules in the asymmetric unit. The four mol­ecules are linked via one O—H⋯N and two N—H⋯N hydrogen bonds, forming a tetra­mer-like unit. In the crystal, mol­ecules are further linked by O—H⋯N and N—H⋯O hydrogen bonds forming layers parallel to (001). These layers are linked via C—H⋯O hydrogen bonds and a number of weak C—H⋯π inter­actions, forming a three-dimensional structure. The crystal was refined as a non-merohedral twin with a minor twin component of 0.319.
