In the paper by Manikandan et al. [IUCrData (2017). 2, x170376], a proton on the indole N was missed in the structure solution. The proton is now added and the changes are reported here. The title, scheme, Figs. 1[link] and 2[link], the hydrogen-bonding table, the crystallographic data table and description of the supra­molecular architectures are corrected.

Structure description

In the paper by Manikandan et al. (2017[Manikandan, D., Gomathi, S., Nirmalram, J. S., Tagore, S. S., Sethuraman, V., Agim, J. & Butcher, R. J. (2017). IUCrData, 2, x170376.]), 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[link], 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[link]), forming zigzag supra­molecular C(9) chains extending along the b-axis direction, as shown in Fig. 2[link]a.' should be replaced by `In the crystal, neighboring mol­ecules self-assemble through N—H⋯N and weak C—H⋯Cl inter­actions (Table 1[link]), resulting in an R33(23) ring motif, which forms a supra­molecular sheet extending along the b axis, as shown in Fig. 2[link]a.' Revised experimental details are given in Table 2[link].

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.
