3-Chloro-N'-[(2-hydroxynaphthalen-1-yl)methylidene]benzohydrazide

T.-Y. Li and W. Li

Abstract top

The title compound, C18H13ClN2O2, was prepared by the reaction of 2-hydroxy-1-naphthaldehyde with 3-chlorobenzohydrazide in methanol. An intramolecular O-H...N hydrogen bond influences the molecular conformation; the benzene ring and naphthyl ring system form a dihedral angle of 17.1 (3)°. In the crystal, intermolecular N-H...O hydrogen bonds link the molecules into chains propagated in [101].

Comment top

In the last years, a number of Schiff bases derived from the reaction of aldehydes with benzohydrazides were prepared and structurally characterized (Bessy et al., 2006; Podyachev et al., 2007; Raj & Kurup, 2007; Pouralimardan et al., 2007; Bacchi et al., 2006; Dinda et al., 2002). As a contribution to this work, we present here the title new Schiff base compound (Fig. 1).

There is an intramolecular O—H···N hydrogen bond in the molecule, which influences the molecular conformation - the dihedral angle between the benzene ring and the naphthyl ring is 17.1 (3)°. All the bond lengths are within normal values (Allen et al., 1987). In the crystal structure, intermolecular N—H···O hydrogen bonds (Table 1) link the molecules into chains propagated in [101] (Fig. 2).

Experimental top

The compound was prepared and crystallized according to the literature method (Zhu, 2010). 2-Hydroxy-1-naphthaldehyde (0.172 g, 1 mmol) and 3-chlorobenzohydrazide (0.171 g, 1 mmol) were dissolved in 30 ml absolute methanol. The mixture was stirred at reflux for 10 min, and cooled to room temperature. The clear colorless solution was left to slow evaporation in air for five days, yielding colorless block-shaped crystals, which were collected by filtration and washed with methanol.

Refinement top

The amino H atom was located from a difference Fourier map and refined isotropically, with the N—H distance restrained to 0.90 (1) Å. The other H atoms were positioned geometrically and refined using the riding-model approximation, with C—H = 0.93 Å, and O—H = 0.82 Å, and Uiso(H) = 1.2Ueq(C) or Uiso(H) = 1.5Ueq(O).

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.
