N'-Cyclohexylidene-2-hydroxybenzohydrazide

D. Liu

Abstract top

In the title molecule, C13H16N2O2, the cyclohexylidene ring adopts a chair conformation. The intramolecular N-H...O hydrogen bond influences the molecular conformation: the benzene ring and the mean plane of the central C(O)NHN fragment form a dihedral angle of 4.9 (1) Å. In the crystal, intermolecular O-H...O hydrogen bonds link the molecules into chains propagated along [001].

Comment top

Chemistry of Schiff bases has been intensively investigated in recent years, owing to their coordination properties and diverse applications. Schiff base derivatives and their complexes have been studied for their antifungal and antibacterial activ- ity, and as antiviral drugs (Sreeja et al., 2003). In this paper, we present the crystal structure of the title compound, (I), which was synthesized by the reaction of cyclohexanone and salicyloyl hydrazide.

In (I) (Fig. 1), the bond lengths and angles are normal and comparable to those observed in the compound reported by Luo et al. (2007). The cyclohexylidene ring adopts a chair conformation. Intramolecular N—H···O hydrogen bond (Table 1) influences the molecular conformationthe - dihedral angle between the benzene ring and the plane C1/N1/N2 is 4.9 (1) Å. The plane C1/N1/N2 and ring C8-C13 form a dihedral angle of 37.7 (3) Å. Intermolecular O—H···O hydrogen bonds (Table 1) link the molecules into chains propagated in direction [001].

Experimental top

Salicyloyl hydrazide (5 mmol) and cyclohexanone (5 mmol),20 ml e nthanol were mixed in 50 ml flash. After stirring 30 min at 353 K, the mixture then cooling slowly to room temperature and affording the title compound, then recrystallized from ethanol, affording the title compound as a red crystalline solid. Elemental analysis: calculated for C13H16N2O2: C 67.22, H 6.94, N 12.06%; found: C 67.29, H 6.85, N 12.24%.

Refinement top

All H atoms were placed in geometrically idealized positions (N—H 0.86 Å, O—H 0.82 Å and C—H=0.93–0.97 Å) and treated as riding on their parent atoms, with Uiso(H) = 1.2-1.5Ueq of the parent atom. In the absence of any significant anomalous scatterers in the molecule, 330 Friedel pairs were merged before the final refinement.

Special details top

Geometry. All e.s.d.'s (except the e.s.d. in the dihedral angle between two l.s. planes) are estimated using the full covariance matrix. The cell e.s.d.'s are taken into account individually in the estimation of e.s.d.'s in distances, angles and torsion angles; correlations between e.s.d.'s in cell parameters are only used when they are defined by crystal symmetry. An approximate (isotropic) treatment of cell e.s.d.'s is used for estimating e.s.d.'s involving l.s. planes.

Refinement. Refinement of F2 against ALL reflections. The weighted R-factor wR and goodness of fit S are based on F2, conventional R-factors R are based on F, with F set to zero for negative F2. The threshold expression of F2 > σ(F2) is used only for calculating R-factors(gt) etc. and is not relevant to the choice of reflections for refinement. R-factors based on F2 are statistically about twice as large as those based on F, and R- factors based on ALL data will be even larger.
