N′-[(E)-2-Meth-oxy-benzyl-idene]pyrazine-2-carbohydrazide

Abstract

In the title compound, C 13H 12N 4O 2, all the non-H atoms lie on a crystallographic mirror plane and an intra-molecular N - H⋯N hydrogen bond generates an S(5) ring; the conformation about the imine bond [1.280 (3) Å] is E. In the crystal, mol-ecules assemble into a two-dimensional array via C - H⋯O(carbon-yl) and C - H⋯N(pyrazine) contacts. Layers stack along the b-axis direction via weak π-π inter-actions between pyrazine rings [ring centroid distance = 3.8028 (8) Å]. © Souza et al. 2011.
