title: (E)-Ethyl N'-(3,4,5-trimethoxy-benzyl-idene)hydrazinecarboxyl-ate.
abstract: The mol-ecule of the title compound, C(13)H(18)N(2)O(5), adopts a trans configuration with respect to the C=N bond. The dihedral angle between the benzene ring and the hydrazinecarboxylic acid plane is 49.75 (5)° and an intra-molecular C-H⋯O inter-action occurs. In the crystal structure, the mol-ecules are linked into a chain along [010] by N-H⋯O hydrogen bonds, and a C-H⋯π contact further stabilizes the structure.
