Abstract top

In the title compound, C15H10ClN3O2, the benzene ring is slightly twisted out of the plane of the 2,3-di­hydro-1H-indole ring system (r.m.s. deviation = 0.007 Å), forming a dihedral angle of 7.4 (3)°. An intra­molecular N-H...O hydrogen bond forms a six-membered ring. In the crystal, mol­ecules are linked via N-H...O and C-H...O hydrogen bonds, forming layers alternately perpendicular to [011] and [0-11].

Comment top

Hydrazide compounds and their condensation products exhibit a wide range of biological activities such as anti-cancer (Strappaghetti et al., 2006), anti-depressant (Al-Assar et al., 2002), anti-HIV (Adekunle et al., 2012), analgesic-anti-inflammatory (Jain & Vederas, 2004), bactericidal (Jeeworth et al., 2000), leishmanicidal (Scozzafava et al., 2001), anti-helmintic (Dharmaraj et al., 2001) and anti-tuberculosis activities (Siddappa et al., 2008). Based on such findings and continuing to our on-going study of the synthesis of bio-active heterocyclic compounds, we herein report on the synthesis and crystal structure of the title compound.

In the title compound, Fig. 1, the intramolecular N1—H1···O2 hydrogen bond forms a pseudo-six-membered ring. The nine non-H ring atoms of the fused five- and six-membered ring system are almost coplanar (r.m.s. deviation = 0.007 Å). The benzene ring and the 2,3-dihydro-1H-indole ring system make a dihedral angle of 7.4 (3)° .

In the crystal structure, molecular layers formed by N—H···O and C-H···O hydrogen bonds are alternately perpendicular to [011] and to [0–11] directions (Table 1 and Fig. 2).

Experimental top

A mixture of 1 mmol (170.6 mg) 4-chlorobenzohydrazidean and 1 mmol (147 mg) 1H-indole-2,3-dione in 25 ml ethanol with few drops of glacial acetic acid was refluxed for 5h. The solid formed was collected and recrystallized from DMF to furnish the title compound as yellow crystals suitable for X-ray analysis [M.p. 558 K].

Refinement top

The NH H atoms (H1 on N1) was located in a difference Fourier map and refined with a distance restraint: N1—H1 = 0.90 (5) Å with Uiso(H) = 1.2Ueq(N). The remaining H atoms were placed in calculated positions and refined using a riding model approximation: C—H = 0.95 Å and N—H = 0.91 Å with Uiso(H) = 1.2Ueq(C, N). The small proportion of reflections observed is a result of the rather poor quality of the very thin crystals obtained.

Special details top

Geometry. Bond distances, angles etc. have been calculated using the rounded fractional coordinates. All su's are estimated from the variances of the (full) variance-covariance matrix. The cell e.s.d.'s are taken into account in the estimation of distances, angles and torsion angles

Refinement. Refinement on F2 for ALL reflections except those flagged by the user for potential systematic errors. Weighted R-factors wR and all goodnesses of fit S are based on F2, conventional R-factors R are based on F, with F set to zero for negative F2. The observed criterion of F2 > σ(F2) is used only for calculating -R-factor-obs 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.
