Comment
We report here the structure of 4-iodo-N,N-bis(2-nitrophenylsulfonyl)aniline, (I) (Fig. 1), where the supramolecular aggregation proves to be markedly different from that in the isomeric compound 4-iodo-N,N-bis(3-nitrophenylsulfonyl)aniline, (II), which was reported recently as part of a wider study of intermolecular interactions in iodonitroarenesulfonamides (Kelly et al., 2002). In (II), the molecules lie across twofold rotation axes in the C2/c, and they are linked into sheets by a combination of a C—H⋯O=S hydrogen bond and a three-centre iodo–sulfonyl interaction, but the nitro O atoms play no role in the intermolecular aggregation.
In (I), the molecules have a planar coordination at atom N1. The molecular conformation is defined by eight torsion angles (Table 1), and these show that the molecules do not exhibit even approximate rotational symmetry; in particular, the orientations of the nitrated aryl rings and the nitro groups are very different for the two independent 2-nitrophenylsulfonyl units within the molecule.
There are no iodo–nitro or iodo–sulfonyl interactions nor aromatic π–π stacking interactions in the structure of (I); instead, the molecules are linked into a complex three-dimensional framework by a combination of six independent C—H⋯O hydrogen bonds (Table 2). However, the formation of the structure of (I) can be analysed in terms of three one-dimensional substructures.
In the first x, y, z) act as donors, respectively, to atoms O21 and O22 in the molecules at (x, y, 1 + z) and (1 − x, 1 − y, 2 − z), and propagation by translation and inversion of these two hydrogen bonds generates a chain of edge-fused rings running parallel to the [001] direction, with R22(18) rings (Bernstein et al., 1995) centred at (, , n) (n = zero or integer) and R44(14) rings centred at (, , + n) (n = zero or integer) (Fig. 2).
which is built from the two shortest hydrogen bonds, atoms C13 and C14 in the molecule at (The second x, y, z) act as hydrogen-bond donors, respectively, to nitro atoms O221 and O222 in the molecule at (1 − x, 1 − y, 1 − z), so forming a centrosymmetric motif in which an R22(22) ring surrounds an R22(18) ring (Fig. 3). At the same time, atom C26 at (x, y, z) acts as a hydrogen-bond donor to sulfonyl atom O11 in the molecule at (−x, 1 − y, 1 − z), so forming a centrosymmetric R22(14) motif. Propagation by inversion of these three hydrogen bonds generates a chain of edge-fused rings running parallel to the [100] direction, with R22(18) and R22(22) rings centred at ( + n, , ) (n = zero or integer) and R22(14) rings centred at (n, , ) (n = zero or integer) (Fig. 4).
depends solely on inversion operations. Atoms C2 and C15 in the molecule at (The combination of the [001] and [100] chains (Figs. 2 and 4) generates a sheet lying parallel to (010) and occupying the domain < y < ; a second sheet, related to the first by the action of the translational symmetry elements, occupies the domain − < y < , and the action of the third and final one-dimensional is to link adjacent (010) sheets. Atom C23 in the molecule at (x, y, z), which forms part of the sheet in the domain < y < , acts as a hydrogen-bond donor to sulfonyl atom O22 in the molecule at (x, − y, − + z), which itself forms part of the sheet in the domain − < y < . Hence, propagation of this hydrogen bond produces a C(6) chain running parallel to the [010] direction and generated by the c-glide plane at y = (Fig. 5), whose effect is to link adjacent (010) sheets, thereby forming a continuous three-dimensional framework structure.
The C—H⋯O hydrogen bonds in (I) (Table 2) utilize three of the four sulfonyl O atoms as acceptors, with atom O22 acting as a double acceptor; while both O atoms of one of the nitro groups are employed as hydrogen-bond acceptors, those in the other nitro group play no role in the supramolecular aggregation. In almost all respects, therefore, the direction-specific intermolecular interactions in isomers (I) and (II) are different, leading to markedly different supramolecular structures.

We report here the structure of N,N-bis-(2-nitrophenylsulfonyl)-4-iodoaniline, (I) (Fig. 1), where the supramolecular aggregation proves to be markedly different from that in the isomeric compound N,N-bis-(3-nitrophenylsulfonyl)-4-iodoaniline, (II), which was reported recently as part of a wider study of intermolecular interactions in iodonitroarenesulfonamides (Kelly et al., 2002). In (II), the molecules lie across twofold rotation axes in space group C2/c, and they are linked into sheets by a combination of a C—H···O═S hydrogen bond and a three-centre iodo–sulfonyl interaction, but the nitro O atoms play no role in the intermolecular aggregation.
In the title compound, (I), the molecules have planar coordination at atom N1. The molecular conformation is defined by eight torsion angles (Table 1), and these show that the molecules do not exhibit even approximate rotational symmetry; in particular, the orientations of the nitrated aryl rings and the nitro groups are very different for the two independent 2-nitrophenylsulfonyl units within the molecule.
There are no iodo–nitro or iodo–sulfonyl interactions nor aromatic π–π stacking interactions in the structure of (I); instead the molecules are linked into a complex three-dimensional framework by a combination of six independent C—H···O hydrogen bonds (Table 2). However, the formation of the structure of (I) can be analysed in terms of three one-dimensional substructures.
In the first substructure, which is built from the two shortest hydrogen bonds, atoms C13 and C14 in the molecule at (x, y, z) act as donors, respectively, to atoms O21 and O22 in the molecules at (x, y, 1 + z) and (1 − x, 1 − y, 2 − z), and propagation by translation and inversion of these two hydrogen bonds generates a chain of edge-fused rings running parallel to the [001] direction, with R22(18) rings (Bernstein et al., 1995) centred at (1/2, 1/2, n) (n = zero or integer) and R44(14) rings centred at (1/2, 1/2, 0.5 + n) (n = zero or integer) (Fig. 2).
The second substructure depends solely on inversion operations. Atoms C2 and C15 in the molecule at (x, y, z) act as hydrogen-bond donors, respectively, to nitro atoms O221 and O222 in the molecule at (1 − x, 1 − y, 1 − z), so forming a centrosymmetric motif in which an R22(22) ring surrounds an R22(18) ring (Fig. 3). At the same time, atom C26 at (x, y, z) acts as hydrogen-bond donor to sulfonyl atom O11 in the molecule at (−x, 1 − y, 1 − z), so forming a centrosymmetric R22(14) motif, and propagation by inversion of these three hydrogen bonds generates a chain of edge-fused rings running parallel to the [100] direction, with R22(18) and R22(22) rings centred at (1/2 + n, 1/2, 1/2) (n = zero or integer) and R22(14) rings centred at (n, 1/2, 1/2) (n = zero or integer) (Fig. 4).
The combination of the [001] and [100] chains (Figs. 2 and 4) generates a sheet lying parallel to (010) and occupying the domain 0.25 < y < 0.75; a second sheet, related to the first by the action of the translational symmetry elements, occupies the domain −0.25 < y < 1/4, and the action of the third and final one-dimensional substructure is to link adjacent (010) sheets. Atom C23 in the molecule at (x, y, z), which forms part of the sheet in the domain 0.25 < y < 3/4, acts as hydrogen-bond donor to sulfonyl atom O22 in the molecule at (x, 1/2 − y, −1/2 + z), which itself forms part of the sheet in the domain −0.25 < y < 0.25. Hence propagation of this hydrogen bond produces a C(6) chain running parallel to the [010] direction and generated by the c-glide plane at y = 0.25 (Fig. 5), whose effect is to link adjacent (010) sheets, thereby forming a continuous three-dimensional framework structure.
The C—H···O hydrogen bonds in (I) (Table 2) utilize three of the four sulfonyl O atoms as acceptors, with O22 acting as a double acceptor; while both O atoms of one of the nitro groups are employed as hydrogen-bond acceptors, those in the other nitro group play no role in the supramolecular aggregation. In almost all respects, therefore, the direction-specific intermolecular interactions in isomers (I) and (II) are different, leading to markedly different supramolecular structures.
