Structure description

In the paper by Manikandan et al. (2017 ), a proton on the indole N atom was missed in the structure solution. The proton has been added and the changes are reported here. The title and the chemical name of the compound should be `3-(4-Chlorobutyl)-1H-indole-5-carbonitrile'.

The proton on the indole nitrogen (N1) is involved in an N—H⋯N hydrogen bond with symmetry-related neighboring molecules and forms an R₃³(23) ring motif instead of a chain with a C(9) graph set.

The figure caption of Fig. 2, the hydrogen-bonding table and the crystallographic data table are updated. In the structure description section, the sentence `In the crystal, neighboring molecules self-assemble through weak C—H⋯Cl interactions (Table 1), forming zigzag supramolecular C(9) chains extending along the b-axis direction, as shown in Fig. 2a.' should be replaced by `In the crystal, neighboring molecules self-assemble through N—H⋯N and weak C—H⋯Cl interactions (Table 1), resulting in an R₃³(23) ring motif, which forms a supramolecular sheet extending along the b axis, as shown in Fig. 2a.' Revised experimental details are given in Table 2.

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 esds 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 > 2sigma(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.
