Abstract

In the title compound, C9H11N3O3, two mol­ecules are present in the asymmetric unit in which the 4-hy­droxy-3-meth­oxy­benzaldehyde and hydrazinecarboxamide units are almost planar [with r.m.s. deviations 0.0212 and 0.0066 Å, respectively, in one mol­ecule and 0.0346 and 0.0095 Å, respectively, in the other] and are oriented at dihedral angles of 9.7 (3) and 16.6 (3)°. In both mol­ecules, two S(5) ring motifs are present due to N—H⋯N and O—H⋯O hydrogen bonds. In the crystal, the mol­ecules are dimerized with each other due to pairs of N—H⋯O hydrogen bonds, forming an R22(8) ring motif. O—H⋯O hydrogen bonds lead to the formation of a three-dimensional network.
