Nicotinohydrazide
Acta Crystallogr Sect E Struct Rep Online 2007 Dec 18;64(Pt 1):o302-3.PMID:21200867DOI:10.1107/S160053680706655X.
The title mol-ecule (alternative name: pyridine-3-carbohydrazide; C(6)H(7)N(3)O) was obtained from the reaction of ethyl nicotinate with hydrazine hydrate in methanol. In the amide group, the C-N bond is relatively short, suggesting some degree of electronic delocalization in the mol-ecule. The stabilized conformation may be compared with those of isomeric compounds picolinohydrazide (pyridine-2-carbohydrazide) and isonicotinohydrazide (pyridine-4-carbohydrazide). In the title isomer, the pyridine ring forms an angle of 33.79 (9)° with the plane of the non-H atoms of the hydrazide group. This lack of coplanarity between the hydrazide functionality and the pyridine ring is considerably greater than that observed in isonicotinohydrazide (dihedral angle = 17.14°), while picolinohydrazide is almost fully planar. The title isomer forms inter-molecular N-H⋯O and N-H⋯N hydrogen bonds, which stabilize the crystal structure.
N'-(Propan-2-yl-idene)Nicotinohydrazide
Acta Crystallogr Sect E Struct Rep Online 2009 Sep 5;65(Pt 10):o2335.PMID:21577806DOI:10.1107/S1600536809034734.
Crystals of the title compound, C(9)H(11)N(3)O, were obtained from a condensation reaction of Nicotinohydrazide and acetone. In the mol-ecular structure, the pyridine ring is oriented at a dihedral angle of 36.28 (10)° with respect to the amide plane. In the crystal structure, mol-ecules are linked via N-H⋯O hydrogen bonds, forming chains.
(E)-N'-[(2-Hydroxynaphthalen-1-yl)methylidene]Nicotinohydrazide
Acta Crystallogr Sect E Struct Rep Online 2011 Jul 1;67(Pt 7):o1756.PMID:21837138DOI:10.1107/S1600536811023257.
In the mol-ecule of the title compound, C(17)H(13)N(3)O(2), the naphthyl ring system and the pyridine ring form a dihedral angle of 12.2 (3)°. An intra-molecular O-H⋯N hydrogen bond generates a six-membered ring with an S(6) ring motif. This also contributes to the relative overall near planarity of the mol-ecule [r.m.s. deviation of all 22 non-H atoms = 0.107 (5) Å]. In the crystal, mol-ecules are linked through inter-molecular N-H⋯N hydrogen bonds, forming chains along the a axis.
(E)-N'-(3,5-Dibromo-2-hydroxy-benzyl-idene)Nicotinohydrazide
Acta Crystallogr Sect E Struct Rep Online 2010 Feb 20;66(Pt 3):o670.PMID:21580418DOI:10.1107/S1600536810006276.
In the title Schiff base compound, C(13)H(9)Br(2)N(3)O(2), there is an intra-molecular O-H⋯N hydrogen bond involving the hydroxyl substituent and the adjacent hydrazine N atom. The mol-ecule is almost planar, the dihedral angle between the benzene ring and the pyridine ring being 5.7 (2)°. In the crystal structure, symmetry-related mol-ecules are linked via N-H⋯O hydrogen bonds, forming chains propagating in [001].
(E)-N'-(3,4-Di-meth-oxy-benzyl-idene)Nicotinohydrazide monohydrate
Acta Crystallogr Sect E Struct Rep Online 2014 Jun 18;70(Pt 7):o793-4.PMID:25161576DOI:10.1107/S1600536814013798.
In the title hydrated compound, C15H15N3O3·H2O, the Nicotinohydrazide mol-ecule adopts a trans conformation with respect to the C=N double bond. The dihedral angle between the benzene and pyridine rings is 5.10 (14)°. In the crystal, the solvent water mol-ecule acts as an acceptor, forming an N-H⋯O hydrogen bond supported by two C-H⋯O contacts. It also acts as a donor, forming bifurcated O-H⋯(O,O) and O-H⋯N hydrogen bonds that combine with the former contacts to form zigzag chains of mol-ecules along the c-axis direction. An additional O-H⋯O donor contact completes a set of six hydrogen bonds to and from the water mol-ecule and connects it to a third Nicotinohydrazide mol-ecule. This latter contact combines with weaker C-H⋯O hydrogen bonds supported by a C-H⋯π contact to stack mol-ecules along b in a three-dimensional network.
