Crystal structure of 2-hy-droxy-imino-2-(pyridin-2-yl)-N'-[1-(pyridin-2-yl)ethyl-idene]acetohydrazide.

ABSTRACT: The mol-ecule of the title compound, C14H13N5O2, is approximately planar (r.m.s deviation for all non-H atoms = 0.093?Å), with the planes of the two pyridine rings inclined to one another by 5.51?(7)°. The oxime group is syn to the amide group, probably due to the formation of an intra-molecular N-H?N hydrogen bond that forms an S(6) ring motif. In the crystal, mol-ecules are linked by pairs of bifurcated O-H?(O,N) hydrogen bonds, forming inversion dimers. The latter are linked via C-H?O and C-H?N hydrogen bonds, forming sheets lying parallel to (502). The sheets are linked via ?-? stacking inter-actions [inter-centroid distance = 3.7588?(9)?Å], involving the pyridine rings of inversion-related mol-ecules, forming a three-dimensional structure.

The mol-ecule of the title compound, C14H13N5O2, is approximately planar (r.m.s deviation for all non-H atoms = 0.093 Å), with the planes of the two pyridine rings inclined to one another by 5.51 (7)°. The oxime group is syn to the amide group, probably due to the formation of an intra-molecular N-H⋯N hydrogen bond that forms an S(6) ring motif. In the crystal, mol-ecules are linked by pairs of bifurcated O-H⋯(O,N) hydrogen bonds, forming inversion dimers. The latter are linked via C-H⋯O and C-H  ...[more]
