N'-[(E)-3-Bromo-benzyl-idene]pyrazine-2-carbohydrazide.

ABSTRACT: In the title compound, C12H9BrN4O, the dihedral angle between the aromatic rings is 12.16?(12)°. An intra-molecular N-H?N hydrogen bond closes an S(5) ring. In the crystal, C-H?O hydrogen bonds link the mol-ecules into C(6) chains propagating in [010]. Very weak aromatic ?-? stacking [centroid-centroid separations = 3.9189?(15) and 3.9357?(15)?Å] is also observed.

In the title compound, C12H9BrN4O, the dihedral angle between the aromatic rings is 12.16 (12)°. An intra-molecular N-H⋯N hydrogen bond closes an S(5) ring. In the crystal, C-H⋯O hydrogen bonds link the mol-ecules into C(6) chains propagating in [010]. Very weak aromatic π-π stacking [centroid-centroid separations = 3.9189 (15) and 3.9357 (15) Å] is also observed. ...[more]

N'-[(E)-4-Bromo-benzyl-idene]pyrazine-2-carbohydrazide.

Project description:In the title compound, C12H9BrN4O, the N'-methyl-idene-pyrazine-2-carbohydrazide and 4-bromobenzene groups are oriented at a dihedral angle of 10.57?(7)°. The hydrazide N-H group is involved in intra-molecular N-H?N inter-action, which generates an S(5) motif. A short C-H?O inter-action is formed between the methyl-idene H atom and the carbonyl O atom. It connects mol-ecules into chains extending along [100]. In addition, mol-ecules are arranged into stacks extending along [010] via ?-? inter-actions between pyrazine and benzene rings, with centroid-centroid distances of 3.837?(2) and 3.860?(2)?Å.

N'-[(E)-2,6-Dichloro-benzyl-idene]pyrazine-2-carbohydrazide.

Project description:The title compound, C(12)H(8)Cl(2)N(4)O, is non-planar, the dihedral angle formed between the pendant pyrazine and benzene rings being 12.55?(11)°. An intra-molecular N-H?N hydrogen bond occurs. The amide groups self-associate via N-H?O hydrogen bonding, forming supra-molecular chains with base vector [101], which are stabilized by C-H?O contacts. C-H?N inter-actions are formed orthogonal to the chains.

2'-(3-Hydroxy-benzyl-idene)pyrazine-2-carbohydrazide monohydrate.

Project description:The title compound, C(12)H(10)N(4)O(2)·H(2)O, was synthesized by the reaction of pyrazine-2-carboxylic acid hydrazide and 3-hydroxy-benzaldehyde in ethanol. In the crystal structure, the organic mol-ecules are linked into extended chains by inter-molecular N(amide)-H?O(hydr-oxy) hydrogen bonds. Additional hydrogen bonds between the water mol-ecule and three adjacent organic mol-ecules, as well as face-to-face ?-? stacking inter-actions between the benzene and pyrazine rings [centroid-to-centroid separation = 3.669?(2)?Å and offset = 1.362?Å], link the mol-ecules into a three-dimensional framework.

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

Project description:In the title compound, C(13)H(12)N(4)O(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 ?-? inter-actions between pyrazine rings [ring centroid distance = 3.8028?(8)?Å].

N'-[(E)-4-Bromo-benzyl-idene]-1-benzofuran-2-carbohydrazide monohydrate.

Project description:The title compound, C(16)H(11)BrN(2)O(2)·H(2)O, exists in a trans conformation with respect to the N=C bond [1.2815 (14) Å] and the benzofuran ring system forms a dihedral angle of 2.96 (5)° with the benzene ring. In the crystal, the ketone O atom accepts two O-H⋯O and one C-H⋯O hydrogen bond, and the water O atom accepts an N-H⋯O inter-action. Together, these lead to infinite layers lying parallel to (100).
