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

ABSTRACT: 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.

<i>N</i>'-(2-Hy-droxy-3-meth-oxy-benzyl-idene)pyrazine-2-carbohydrazide monohydrate.

Project description:In the title hydrated Schiff base, C13H12N4O3·H2O, the dihedral angle between the aromatic rings is 5.06 (11)° and an intra-molecular O-H⋯N hydrogen bond closes an S(6) ring. In the crystal, Ow-H⋯O and Ow-H⋯N (w = water) hydrogen bonds link the components into centrosymmetric tetra-mers (two Schiff bases and two water mol-ecules). Longer N-H⋯O hydrogen bonds link the tetra-mers into [010] chains. A weak C-H⋯O hydrogen bond and aromatic π-π stacking between the pyrazine and phenyl rings [centroid-centroid separations = 3.604 (2) and 3.715 (2) Å] are also observed.

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.

N'-[(E)-4-Chloro-benzyl-idene]pyridine-4-carbohydrazide monohydrate.

Project description:The asymmetric unit of the title compound, C(13)H(10)ClN(3)O·H(2)O, consists of two crystallographically independent Schiff base mol-ecules which exist in an E conformation with respect to the C=N double bond, and two independent water mol-ecules.

A C-H?? inter-action is also present.
