In the title compound, C9H6Cl3NO, the pyrrole ring is almost coplanar with the benzene ring [dihedral angle = 1.90 (9)°], while the Cl—C—N—C torsion angle is 98.78 (17)°. In the crystal, pairs of molecules are interconnected by pairs of Cl⋯Cl interactions [3.564 (5) Å], forming dimers, which are further peripherally connected through intermolecular C—H⋯O=C and π–π interactions [centroid–centroid distances = 4.134 (7), 4.134 (6) and 4.238 (7) Å], forming a two-dimensional network.

A mixture of indoline-2,3-dione (3.0 g, 0.02 mol) and formalin (5 ml) in 30 ml of water was refluxed for 1 h. After that, the reaction mixture was stirred at room temperature overnight. The resulting precipitate, 1-(hydroxymethyl)indoline-2,3-dione, was separated by filtration and purified by recrystallization from ethanol, which was heated with SOCl2 (25 ml) under reflux for 3.5 h. The reaction mixture was distilled in vacuum to remove excess SOCl2 and the residue was purified by
on silica gel using dichloromethane/methanol=98:2, v/v, as an (Rf=0.33, dichloromethane/methanol=98:2, v/v; m.p. 141–143°C; yield 50.5% in two steps). The light yellow crystals of the title compound were obtained by slow evaporation from the solution of dichloromethane methanol 98:2 (v/v) at room temperature.All the H atoms were discernible in the difference electron density maps. Nevertheless, the hydrogen atoms were placed into idealized positions and allowed to ride on the carrier atoms, with C—H=0.93 Å for aryl H atoms and Uiso(H)=1.2Ueq(C).
Höhme and Schwartz reported that the reaction of 1-(hydroxymethyl) indoline-2,3-dione with SOCl2 gave 1-(chloromethyl) indoline-2,3-dione (Höhme & Schwartz, 1973), whereas the reaction in the presence of a small amount of pyridine gave the title compound (Höhme & Schwartz, 1974). However, our experimental results showed that the title compound could also be obtained from the reaction in the absence of pyridine. Here, we report the structure of the title compound.
X-ray crystal analysis shows that the pyrrole ring almost lies within the plane of the benzene ring, while the torsion angle Cl2—C9—N1—C8 equals 98.78 (17)°, as shown in Fig.1. Two molecules arrange in a face to face mode and thus interconnect through intermolecular Cl1···Cl2(-x + 1, -y + 1, -z + 2) interactions (Cl···Cl=3.564 (5) Å) (Reddy et al., 2006), forming a dimer. Each dimeric unit peripherically links to four neihgbouring ones through intermolecular C4—H4···O1=C8 interactions (Table 1), generating a two-dimensional network. π–π interactions (Table 2) between the approximate parallel benzene and/or parrole rings cooperate with those weak interactions to consolidate the supramolecular structure, as shown in Fig. 2.

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. |

Höhme and Schwartz reported that the reaction of 1-(hydroxymethyl) indoline-2,3-dione with SOCl2 gave 1-(chloromethyl) indoline-2,3-dione (Höhme & Schwartz, 1973), whereas the reaction in the presence of a small amount of pyridine gave the title compound (Höhme & Schwartz, 1974). However, our experimental results showed that the title compound could also be obtained from the reaction in the absence of pyridine. Here, we report the structure of the title compound.
X-ray crystal analysis shows that the pyrrole ring almost lies within the plane of the benzene ring, while the torsion angle Cl2—C9—N1—C8 equals 98.78 (17)°, as shown in Fig.1. Two molecules arrange in a face to face mode and thus interconnect through intermolecular Cl1···Cl2(-x + 1, -y + 1, -z + 2) interactions (Cl···Cl=3.564 (5) Å) (Reddy et al., 2006), forming a dimer. Each dimeric unit peripherically links to four neihgbouring ones through intermolecular C4—H4···O1=C8 interactions (Table 1), generating a two-dimensional network. π–π interactions (Table 2) between the approximate parallel benzene and/or parrole rings cooperate with those weak interactions to consolidate the supramolecular structure, as shown in Fig. 2.
