2-[(E)-3,4-Dimeth-oxy-benzyl-idene]hydrazinecarboxamide
Abstract:
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.

Nomenclature of Carboxylic Acid Derivatives: Amides and Nitriles
The IUPAC and common names of amides are derived from the parent carboxylic acid, by replacing the suffix “oic acid” and “ic acid,” respectively, with “amide.” In the following example, the IUPAC name ethanamide is derived from ethanoic acid, and the common name, acetamide, is obtained from acetic acid.
