The title compound exists entirely in the keto form in the solid state, although NMR spectroscopy indicates that in solution the enol form is present, The asymmetric unit contains two structurally similar independent molecules and a water molecule of solvation. There is an extensive three-dimensional network of intermolecular hydrogen bonds of types N-H ... O, N-H ... N and OW-H ... O.
