The title compound, C15H9ClN2O2, adopts an E configuration about the C=N double bond. The mean plane of the isoindoline ring system [maximum deviation = 0.011 (2) Å] is inclined to the chlorobenzene ring by 22.62 (8)°. In the crystal, molecules are connected by C—H⋯O hydrogen bonds, forming chains that propagate along [010].

A solution of 2-aminoisoindoline-1,3-dione (0.16 g, 1 mmol) in 15 ml ethanol was added slowly to a solution containing 2-chlorobenzaldehyde (0.14 g,1 mmol) in 5 ml absolute ethanol, under heating and stirring, then the mixture was refluxed for 2 h. The mixture was then cooled to room temperature and the resulting solution left to stand in air for 15 days. Colourless prism-shaped crystals were formed on slow evaporation of the solvent.
All H-atoms were placed in calculated positions and treated as riding: C—H = 0.93 Å, with Uiso(H) = 1.2Ueq(parent C-atom).
Amidrazones have been shown to act as important precursors or intermediates in the synthesis of various chemical compounds widely applied in industry (Neilson et al., 1970), and the amidrazone moiety (C═NN) is an essential part of numerous molecules demonstrating high biological activity (Lee et al., 1998; Radwan et al., 2007). As part of an ongoing study of compounds based on the amidrazone moiety (Xu et al., 2009; Liu et al., 2011), we report herein on the of the title compound, synthesized from 2-aminoisoindoline-1,3-dione and 2-chlorobenzaldehyde.
The molecular structure of the title compound is shown in Fig. 1. The C═N double bond adopts an E configuration. The isoindoline ring system [(N2,C8-C15); maximum deviation 0.011 (2) Å] makes a dihedral angle of 22.62 (8)° with the chorobenzene ring (C1-C6).
In the cystal, molecules are connected by C15-H15···O1 hydrogen bonds forming dimers, which stack along the b-axis direction (Fig. 2).

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 esds are taken into account in the estimation of distances, angles and torsion angles |
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. |

Amidrazones have been shown to act as important precursors or intermediates in the synthesis of various chemical compounds widely applied in industry (Neilson et al., 1970), and the amidrazone moiety (C═NN) is an essential part of numerous molecules demonstrating high biological activity (Lee et al., 1998; Radwan et al., 2007). As part of an ongoing study of compounds based on the amidrazone moiety (Xu et al., 2009; Liu et al., 2011), we report herein on the crystal structure of the title compound, synthesized from 2-aminoisoindoline-1,3-dione and 2-chlorobenzaldehyde.
The molecular structure of the title compound is shown in Fig. 1. The C═N double bond adopts an E configuration. The isoindoline ring system [(N2,C8-C15); maximum deviation 0.011 (2) Å] makes a dihedral angle of 22.62 (8)° with the chorobenzene ring (C1-C6).
In the cystal, molecules are connected by C15-H15···O1 hydrogen bonds forming dimers, which stack along the b-axis direction (Fig. 2).
