چکیده
In the title compound, C(10)H(13)N(3)O(3), the 3,4-dimeth-oxy-benzyl-idene and hydrazinecarboxamide groups are oriented at a dihedral angle of 53.82 (6)° and an intra-molecular N-H⋯N hydrogen bond generates an S(5) ring motif. In the crystal, mol-ecules are linked by N-H⋯O hydrogen bonds into sheets propagating in (-201), which feature R(1) (2)(5), R(2) (2)(8) and R(2) (4)(14) loops.
