title: (E)-Methyl N'-(2-hydroxy-benzyl-idene)-hydrazinecarboxyl-ate at 123 K.
abstract: In the title mol-ecule, C(9)H(10)N(2)O(3), the hydrazinecarboxylic acid mean plane and the benzene ring form a dihedral angle of 11.1 (1)°. In the crystal structure, inter-molecular N-H⋯O hydrogen bonds link the mol-ecules into chains extending along the b axis. An intra-molecular O-H⋯N hydrogen bond is also present.
