(E)-Methyl N′-(2-hydroxy­benzyl­idene)­hydrazinecarboxyl­ate at 123 K

Abstract

In the title mol­ecule, C9H10N2O3, the hydrazinecarboxylic acid mean plane and the benzene ring form a dihedral angle of 11.1 (1)°. In the crystal structure, inter­molecular N—H⋯O hydrogen bonds link the mol­ecules into chains extending along the b axis. An intra­molecular O—H⋯N hydrogen bond is also present
