Abstract
The title compound, C9H8N2O, crystallized with four independent molecules in the asymmetric unit. The four molecules are linkedviaone 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 linkedviaC—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.
