title: (E)-Methyl N'-(3-hy-droxy-benzyl-idene)hydrazinecarboxyl-ate dihydrate.
abstract: The title compound, C(9)H(10)N(2)O(3)·2H(2)O, crystallizes with two organic mol-ecules and four water mol-ecules in the asymmetric unit. Both organic mol-ecules adopt a trans conformation with respect to the C=N bond and are close to planar [dihedral angles between the side chain and the aromatic ring = 9.34 (8) and 4.96 (8)°]. In the crystal, the components are linked into three-dimensional network by N-H⋯O and O-H⋯O hydrogen bonds.
